Trig Substitution Example 2 Youtube The trigonometric substitution integration examples in this integral calculus course are: 1) ∫(x^2 sqrt(25 x^2))dx and 2) ∫(1 (x*sqrt(9 16x^2)))dx. in the fi. Section 7.3 : trig substitutions. as we have done in the last couple of sections, let’s start off with a couple of integrals that we should already be able to do with a standard substitution. ∫x√25x2 − 4dx = 1 75(25x2 − 4)3 2 c ∫ x √25x2 − 4 dx = 1 25√25x2 − 4 c. both of these used the substitution u = 25x2 − 4 and at. It can be shown that this triangle actually produces the correct values of the trigonometric functions evaluated at θ θ for all θ θ satisfying − π 2 ≤ θ ≤ π 2. − π 2 ≤ θ ≤ π 2. it is useful to observe that the expression a 2 − x 2 a 2 − x 2 actually appears as the length of one side of the triangle. Figure 7.3.7: calculating the area of the shaded region requires evaluating an integral with a trigonometric substitution. we can see that the area is a = ∫5 3√x2 − 9dx. to evaluate this definite integral, substitute x = 3secθ and dx = 3secθtanθdθ. we must also change the limits of integration.
