WebJun 13, 2024 · Explanation: Suppose that, I = ∫ sec3x tanx dx. ∴ I = ∫ 1 cos3x ⋅ cosx sinx dx = ∫ 1 cos2xsinx dx. = ∫ sinx cos2x ⋅ sin2x dx, = ∫ sinx cos2x(1 − cos2x) dx, Letting cosx = t, so that, −sinxdx = dt, we have, I = ∫ −1 t2(1 − t2) dt = ∫ 1 t2(t2 − 1) dt, = ∫{ t2 −(t2 − 1) t2(t2 −1) dt, = ∫{ t2 t2(t2 − 1) − t2 − 1 t2(t2 −1) }dt, = ∫{ 1 t2 −1 − 1 t2 }dt, WebCos 3x is an important formula in trigonometry given by cos 3x = 4 cos 3 x - 3 cos x. Now, we will use this formula to calculate the integration of cos 3x. But before this, we will evaluate the integral of cos cube x, that is, determine the value of ∫cos 3 x dx. To determine this integral, we will use trigonometric formulas and identities.

Not the answer you're looking for? WebTo start with this integral, there is a very powerful trick that allows us to solve it, we will multiply the \sec x by a fraction that contains \sec x + \tan x in the denominator and in the numerator. \displaystyle \int \sec x \cfrac{\sec x + \tan x}{\sec x + \tan x} dx. We will do the multiplication and the obtained result will be the following: WebTo find the integral of sec x, we will have to use some facts from trigonometry. Sec x is the reciprocal of cos x and tan x can be written as (sin x)/ (cos x). We can do the integration … rdb child didn\\u0027t terminate
