How to solve integral of sec 3x
WebMay 7, 2024 · 3 As noted here, we can integrate powers of secant with integration by parts, viz. ∫ sec n + 2 x d x = sec n x tan x − n ∫ sec n x tan 2 x d x = sec n x tan x + x + 1 This recursion allows us to go from ∫ 2 x d x = tan x + to ∫ 4 x x 2 x tan x 2 tan x 3 + C.

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,

The integral of sec(x) has been deal with in an earlier post, multiply top and bottom by (sec(x) + tan(x)), and, (use a substitution if you must), it's of the standard form ' the thing on the top is the derivative of the thing on the bottom ' so it integrates directly to the ... Web∫sec3(x)dx Recall the identity sec2(x) = tan2(x) + 1. So, substituting, you get ∫sec(x)(tan2(x) + 1)dx = ∫tan(x)tan(x)sec(x)dx + ∫sec(x)dx. The first integral can be solved by u -substitution and integration by parts, while the second, is an identity. ∫tan(x)dsec(x) = tan(x)sec(x) − ∫sec(x)dtan(x) But ∫ sec(x)dtan(x) is the original integral.
