Expert Answer 100% (7 ratings) Find dy/dx y=tan(x) Differentiate both sides of the equation. The derivative of with respect to is . The derivative of with respect to is . Transcript. Ex 7.2, 21 tan﷮2﷯ (2𝑥 – 3) Let I = ﷮﷮ tan﷮2﷯ (2𝑥 – 3)﷯ . 𝑑𝑥 = ﷮﷮ sec﷮2﷯ 2𝑥 – 3﷯−1﷯ ﷯𝑑𝑥 = ﷮﷮ sec﷮2﷯ 2𝑥 – 3﷯ ﷯𝑑𝑥− ﷮﷮ 1﷯.𝑑𝑥 = ﷮﷮ sec﷮2﷯ 2𝑥 – 3﷯ ﷯𝑑𝑥 − 𝑥+𝐶1 Solving 𝐈1 I1 = ﷮﷮ sec﷮2﷯ 2𝑥 – 3﷯ ﷯𝑑𝑥 Let 2𝑥 – 3=𝑡 Differentiating both You can not integrate tan 2 x but you can integrate sec 2 x Since sec 2 x = 1 + tan 2 x Then tan 2 x = sec 2 x-1 so the intragral of tan 2 x dx = the integral of (sec 2 x-1) dx = intrgral of sec 2 x dx + integral of 1 dx = tanx-x +C In mathematics, trigonometric substitution is the substitution of trigonometric functions for other expressions. In calculus, trigonometric substitution is a technique for evaluating integrals.
