(e^(x)cos3x-4^(x)tan3x)/(4^(x)*cos3x)

Evaluate the following w.r.t x: int frac{ e^x cos 3x - 4^x tan 3x}{4^x cos 3x} dx

int_(, then )^( If )e^(3x)cos4xdx=e^(3x)(A sin4x+B cos4x)+C

int e^(3x)cos4xdx=e^(3x)(A sin4x+B cos4x)+c

The period of (cos(3x+4)+tan(5x+7))/(cos ec(3+4x)-sin(4-6x)) 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))=

Method of integration by parts : inte^(3x)cos 4xdx=e^(3x)(A sin 4x+B cos4x)+c then.....

Prove that: (sin x)/(cos3x)+(sin3x)/(cos9x)+(sin9x)/(cos27x)=((1)/(2))(tan27x-tan x)

Show that: (sin x)/(cos3x)+(sin3x)/(cos9x)+(sin9x)/(cos27x)=(1)/(2)(tan27x-tan x)
