sin x*cos^(3)x

Find the integral 1/(sin x cos ^3x)

Find integration sin x sin2x cos3x

Solve the equations: sin 5x - sin x = cos 3x

the range of the function f defined by f(x)=(sin x cos3x)/(sin3x*cos x)is

The value of (2(sin2x+2cos^(2)x-1))/(cos x sin x cos3x+sin3x) is

If f_(n)(x) = (sin x)/(cos3x)+(sin 3x)/(cos 3^(2)x) +(sin 3^(2)x)/(cos 3^(3)x) +....+ (sin 3^(n-1)x)/(cos 3^(n)x)"Then" f_(2) ((pi)/(4)) + f_(3) ((pi)/(4))=

int(sin x)/(cos3x*cos2x)dx

Number of solution(s) of the equation (sin x)/(cos3x)+(sin3x)/(cos3x)+(sin2x)/(cos27x)=0 in the interval (0,(pi)/(4)) is

The period of sin^(3) x + cos^(3) x is

lim_(x to 0) (sin x + cos 3x)^(2//x) =
