7.2: Trigonometric Integrals. Trigonometric substitution is an integration technique that allows us to convert algebraic expressions that we may not be able to integrate into expressions involving trigonometric functions, which we may be able to integrate using the techniques described in this section. In addition, these types of integrals ...Free Trigonometric Substitution Integration Calculator - integrate functions using the trigonometric substitution method step by step ... trigonometric-substitution-integration-calculator. trigonometric substitution \int \sqrt{49-x^{2}}dx. en. Related Symbolab blog posts.If we choose tan θ, we end up with 9 + tan² θ, which doesn't help much. But when we choose 3 tan θ we get 9 + 9 tan² θ, and that works because we can factor out a 9 and use a trig identity to get 9 sec² θ.
