The seeds of this technique can be traced back to the work of Brook Taylor in the early 18th century. So, your child is learning something that has been refined and used by mathematicians for centuries!
This is where LIATE comes in. It's a mnemonic that helps you prioritize which function to choose as 'u'. LIATE stands for:
The rule suggests that you choose 'u' based on this order. If you have a logarithmic function and an algebraic function, choose the logarithmic function as 'u'.
Example: ∫ x ln(x) dx
Here, we have an algebraic function (x) and a logarithmic function (ln(x)). According to LIATE, we choose u = ln(x) and dv = x dx.
Why does this work? Because differentiating ln(x) gives us 1/x, which simplifies the integral. Integrating x gives us x²/2. Plugging these into the Integration by Parts formula, we get:
∫ x ln(x) dx = ln(x) (x²/2) - ∫ (x²/2) (1/x) dx
= (x²/2)ln(x) - ∫ (x/2) dx
= (x²/2)ln(x) - (x²/4) + C
See? Much simpler!
Interesting Fact: Sometimes, you might need to apply Integration by Parts twice to solve a single problem! Don't be intimidated; just follow the LIATE rule consistently.
The Singapore JC1 H2 Math syllabus often includes problems that require a strategic application of LIATE. Pay close attention to the types of functions presented in the question. The examiners love to test your understanding of this concept! Look out for questions that combine different types of functions within the same integral.
Remember: Practice makes perfect! The more your child practices, the more intuitive this process will become.

And if they need a little extra help, remember there's always singapore junior college 1 h2 math tuition available.
The first crucial step is correctly identifying the 'u' and 'dv' within the integral. This choice significantly impacts the complexity of the subsequent integration. A common strategy is using the LIATE acronym (Logarithmic, Inverse trigonometric, Algebraic, Trigonometric, Exponential) as a guide for prioritizing 'u'. Remember, the goal is to choose 'u' such that its derivative, 'du', simplifies the integral, making it easier to solve. Picking the wrong 'u' can lead to a more complicated integral, so take your time and think it through carefully. This is where many students taking singapore junior college 1 h2 math tuition often make mistakes.
Once you've selected 'u', the next step is to differentiate it with respect to 'x' to find 'du'. This is a straightforward application of differentiation rules that your child should already be familiar with. However, accuracy is paramount here. In the Lion City's vibrant education landscape, where pupils encounter considerable pressure to thrive in numerical studies from elementary to advanced stages, discovering a tuition centre that combines knowledge with genuine zeal can create significant changes in nurturing a appreciation for the subject. Passionate instructors who extend outside mechanical learning to encourage strategic problem-solving and tackling abilities are rare, but they are essential for assisting pupils tackle difficulties in areas like algebra, calculus, and statistics. For families seeking such committed guidance, primary school maths tuition emerge as a symbol of devotion, powered by instructors who are strongly engaged in each pupil's progress. This consistent enthusiasm translates into tailored instructional strategies that adapt to unique requirements, resulting in improved scores and a lasting fondness for math that reaches into prospective educational and professional endeavors.. A small mistake in differentiation can propagate through the rest of the problem, leading to an incorrect answer. Double-check your work, paying close attention to signs and constants. This seems simple, but it's a critical step in the integration by parts process, especially for H2 math.
After identifying 'dv', you need to integrate it with respect to 'x' to find 'v'. In Singapore's rigorous education environment, where English functions as the primary channel of education and assumes a central role in national tests, parents are enthusiastic to help their children tackle common hurdles like grammar influenced by Singlish, lexicon deficiencies, and issues in interpretation or essay creation. Developing robust foundational competencies from early levels can greatly elevate self-assurance in tackling PSLE elements such as contextual composition and spoken communication, while secondary learners profit from focused exercises in textual examination and argumentative papers for O-Levels. For those seeking efficient strategies, exploring English tuition Singapore provides useful insights into courses that match with the MOE syllabus and emphasize interactive education. This extra assistance not only refines assessment skills through mock tests and feedback but also encourages domestic routines like everyday reading plus talks to cultivate enduring language proficiency and scholastic success.. Remember to include the constant of integration, '+C', only at the very end of the entire problem, not at this intermediate step. The integral of 'dv' should be relatively simple; otherwise, you might want to reconsider your initial choice of 'u' and 'dv'. A common mistake here is forgetting basic integration rules or making errors with signs. Accuracy in this step is just as important as in differentiation, so pay close attention. Many Singapore students taking singapore junior college 1 h2 math tuition struggle with this.
Now comes the crucial step of applying the integration by parts formula: ∫u dv = uv - ∫v du. Substitute the expressions you found for 'u', 'v', 'du', and 'dv' into the formula. Be very careful with signs and parentheses, as these are common sources of errors. The goal is to transform the original integral into a new integral (∫v du) that is simpler to solve than the original. If the new integral looks more complicated, it might be a sign that you need to revisit your initial choice of 'u' and 'dv'.
The final step is to simplify the resulting integral and solve it. This might involve using other integration techniques, such as substitution or partial fractions. Don't forget to add the constant of integration, '+C', at the end. Check your answer by differentiating the result; it should give you back the original integrand. A neat and organized presentation of your work will help you avoid errors and make it easier for the examiner to follow your reasoning. Mastering this technique is essential for success in H2 math and beyond, and can even help with future careers involving AI.

However, the formal development of integration as we know it today came with the development of calculus in the 17th century by Isaac Newton and Gottfried Wilhelm Leibniz.
Let's say we want to evaluate ∫₀^(π/2) x cos(x) dx.
Identify 'u' and 'dv': Let u = x (algebraic) and dv = cos(x) dx (trigonometric).
Differentiate 'u' and Integrate 'dv': du = dx and v = sin(x).
Apply the Formula: ∫x cos(x) dx = x sin(x) - ∫sin(x) dx
Evaluate 'uv' at the Limits: [x sin(x)]_0^(π/2) = (π/2)sin(π/2) - (0)sin(0) = π/2
Evaluate the Remaining Integral: ∫₀^(π/2) sin(x) dx = [-cos(x)]_0^(π/2) = -cos(π/2) - (-cos(0)) = 0 - (-1) = 1
Combine and Simplify: ∫₀^(π/2) x cos(x) dx = π/2 - 1
Therefore, the answer is π/2 - 1. See? Not so scary, right?

Integration by Parts is just one tool in the JC1 H2 Math integration toolbox. It's crucial to understand when to use it and how it fits in with other techniques. Here's a quick overview:
Partial fraction decomposition is a technique used to simplify rational functions (fractions where both the numerator and the denominator are polynomials) into simpler fractions. This makes the integration process much easier. The basic idea is to break down a complex fraction into a sum of simpler fractions, each with a denominator that is a factor of the original denominator. The process involves factoring the denominator, setting up the partial fraction decomposition, solving for the unknown constants, and then integrating each resulting term separately.
Understanding when to use each method is key to success in H2 Math. It's like having the right tool for the job – you wouldn't use a hammer to screw in a nail, right?
Interesting Fact: The development of integration techniques has a rich history, dating back to ancient Greece! Mathematicians like Archimedes used ingenious methods to calculate areas and volumes, laying the groundwork for modern calculus.
Now, let's get down to business with some example questions. Remember, kia su (afraid to lose) is part of our culture, but with the right preparation, there's nothing to fear!
