We have since learned a number of integration techniques, including Substitution and Integration by Parts, yet we are still unable to evaluate the above integral without resorting to a geometric interpretation. This section introduces Trigonometric Substitution, a method of integration that fills this gap in our integration skill.Two Key Formulas. From Trigonometry, we have the following two key formulas: sec2 x = 1 +tan2 x (2.2.14) (2.2.14) sec 2 x = 1 + tan 2 x. so. and. tan2 x = sec2 x − 1 (2.2.16) (2.2.16) tan 2 x = sec 2 x − 1. so. x = sec 2 x − 1. When we have integrals that involve any of the above square roots, we can use the appropriate substitution.Calculus 2 6 units · 105 skills. Unit 1 Integrals review. Unit 2.

Definite Integrals Method: Define the limits of integration for the integral of cos^2 theta. Apply one of the above methods (trigonometric identities, integration by parts, or substitution) to evaluate the indefinite integral of Cos^2 θ.First make the substitutions x = 2sinθ and dx = 2cosθdθ. Since sinθ = x 2, we can construct the reference triangle shown in Figure 3. Figure 2.3.3: A reference triangle can be constructed for Example. Thus, ∫ √4 − x2 x dx = ∫ √4 − (2sinθ)2 2sinθ 2cosθdθ Substitute x = 2sinθ and dx = 2cosθdθ.Something of the form 1/√ (a² - x²) is perfect for trig substitution using x = a · sin θ. That's the pattern. Sal's explanation using the right triangle shows why that pattern works, "a" is the hypotenuse, the x-side opposite θ is equal to a · sin θ, and the adjacent side √ (a² - x²) is equal to a · cos θ .No. As we saw in class, you can use trig substitution even when you don’t have square roots. In particular, if you have an integrand that looks like an expression inside the square roots shown in the above table, then you can use trig substitution. You should only do so if no other technique (e.g., u-substitution) works. Here are some examples. 1CalculusTechniques of IntegrationIntegration by Trigonometric Substitution. Key Questions.

We can generalize the procedure in the following Problem-Solving Strategy.The idea behind the trigonometric substitution is quite simple: to replace expressions involving square roots with expressions that involve standard trigonometric functions, but no square roots. Integrals involving trigonometric functions are often easier to solve than integrals involving square roots. Let us demonstrate this idea in practice.Integration by substitution is a useful method to find the antiderivatives of functions that involve the composition of two functions.
