The substitution technique, also known as u-substitution, is a fundamental tool in integration. It's like finding a hidden key to unlock a complex integral. The goal is to simplify the integral by replacing a part of the integrand with a new variable, 'u', and its differential, 'du'.
Example: Consider the integral ∫2x * cos(x2) dx. Let u = x2, then du = 2x dx. Substituting, we get ∫cos(u) du, which is much easier to solve. The result is sin(u) + C, and substituting back gives sin(x2) + C.
Integration by parts is your friend when you're faced with the integral of a product of two functions. The formula is ∫u dv = uv - ∫v du. The trick is choosing 'u' and 'dv' wisely. The LIATE rule (Logarithmic, Inverse trigonometric, Algebraic, Trigonometric, Exponential) is a helpful guide. Choose 'u' as the function that comes earlier in the list.
Example: Consider the integral ∫x * sin(x) dx. Let u = x and dv = sin(x) dx. Then, du = dx and v = -cos(x). Applying the formula, we get -x*cos(x) - ∫-cos(x) dx = -x*cos(x) + sin(x) + C.
Interesting Fact: Integration by parts was developed by Brook Taylor, an English mathematician, in the early 18th century. It's a testament to how long these mathematical tools have been around and how essential they remain!
