int(cos x*dx)/(8+cos^(2)x)

" (8) "int(sin x)/(cos^(2)x)dx

Find the following integrals: ( i ) int(sin x+cos x)dx( ii) int cos ecx(cos ecx+cos x)dx( iii) int(1-sin x)/(cos^(2)x)dx

int(cos(x+a)dx)/cos(x+b)

int(cos x)/(cos(x+a))dx

int_(0)^(pi//2) (8+7 cos x )/((7+8 cos x)^(2))dx is equal to

int(cos x-cos2x)/(1-cos x)*dx

Show that int_(0)^(pi//2)(sin x cos x)/(cos^(2) x + 3 cos x + 2) dx = log (9/8)

Show that int_(0)^(pi//2)(sin x cos x)/(cos^(2) x + 3 cos x + 2)dx = log((9)/(8))

Evaluate : (i) int (cos2x+2sin^2x)/(sin^2x)dx (ii) int(2cos^2x-cos2x)/(cos^2x)dx

int((sin x cos x))/(cos2x)dx
