In calculus, integration by substitution, also known as u-substitution, reverse chain rule or change of variables, [1] is a method for evaluating integrals and antiderivatives. It is the counterpart to the chain rule for differentiation, and can loosely be thought of as using the chain rule "backwards."Using area and one side for right triangle trig calculation. If you know a a or b b, use the right triangle area formula that relates the base ( b b) to the height ( a a) and solve for the unknown side: Given a: b = 2 × Area / a. b = 2 \times \text {Area}/a b =2×Area/a; and. Given b:In this section we discuss substitutions that simplify integrals containing square roots of the form \begin{align*} \sqrt{a^2-x^2} && \sqrt{a^2+x^2} && \sqrt{x^2-a^2}. \end{align*} When the integrand contains one of these square roots, then we can use trigonometric substitutions to eliminate them. That is, we substituteWhile it might look like a simple, non-trigonometric u -substitution is viable here, it's not. We want 25 9 x2 = 4sin2θ, so we make the substitution 5 3x = 2sinθ, which leads to 5 3 dx = 2cosθdθ. Solving this for dx, we get dx = 6 5cosθdθ.
