This is where the magic happens! The key is to identify a part of the integrand (the expression inside the integral) whose derivative is also present (up to a constant multiple). This is where your eagle eyes need to come into play. Think of it like this: you're looking for a function and its "shadow" lurking within the integral.
Once you've chosen your 'u', find its derivative with respect to x. This is straightforward differentiation. In our example, if u = x2 + 1, then du/dx = 2x. This step is crucial because it links 'u' and 'x', allowing you to rewrite the entire integral in terms of 'u'.
This is where you rewrite the original integral using 'u' and 'du'. From du/dx = 2x, we get du = 2x dx. Now, substitute 'u' and 'du' into the original integral: ∫(x2+1)5 (2x dx) becomes ∫u5 du. Notice how much simpler that looks? *So simple can liao!*
Finally, replace 'u' with its original expression in terms of 'x'. This gives you the solution in terms of the original variable. In our example, (u6)/6 + C becomes ((x2+1)6)/6 + C. And there you have it – the integral solved! You've successfully navigated the substitution method. Go treat yourself to some bubble tea; you deserve it!
This method is useful for integrating products of functions. It's based on the product rule for differentiation. Formula: ∫udv = uv - ∫vdu. Choose u and dv carefully to simplify the integral. Think of it as a strategic partnership – choose the right partners, and you'll conquer the integral!
This method involves substituting trigonometric functions for expressions involving square roots of the form √(a2 - x2), √(a2 + x2), or √(x2 - a2). It's particularly useful when dealing with integrals involving circles, ellipses, or hyperbolas. These substitutions leverage trigonometric identities to simplify the integral.
