Nettet13. jun. 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, Nettet30. jun. 2024 · First term should have d/dx(secx)=tanx.secx multipled, i.e. first term is 2sec 2 x.tanx.
