NettetTrigonometric substitution is an application of the Inverse Substitution Rule used to evaluate integrals containing expressions of the form \[\sqrt{x^2+a^2},\quad \sqrt{a^2-x^2},\quad \text{and} \quad \sqrt{x^2-a^2}.\] It involves replacing \(x\) with a trigonometric function, allowing these problematic expressions to be rewritten using trigonometric … NettetExample 2. Evaluate ∫ x 2 − 25 x 2 x d x. Solution. We can see that the integral we want to evaluate has x 2 – 25, so this belongs to the third form ( x 2 + a 2) that meets the conditions for the trigonometric substitution method. In fact, for this case, we can let x be a sec θ, where a = 5. NettetFor example, the definite integral may be evaluated by substituting , with the bounds determined using . Since and , On the other hand, direct application of the boundary … fg117p00clr
