`intdx/sqrt (13+5cosx-12sinx)`

intdx/(sqrt (3)cosx+sinx)

intdx/(cosx-sinx)

int(dx)/(13+3 cosx+4sinx)=

intdx/(sinx(3+2cosx))

intdx/(sinx(3+2cosx))

intdx/(sinx(3+2cosx))

sqrt(3)cosx+sinx=1

Evaluate the following: intdx/(sqrt(sin^3x(sinx+2cosx)

If f(x)=cos^(-1)(1/sqrt(13)(2cosx-3sinx)) +sin^(-1)(1/sqrt(13)(2cosx+3sinx)) , then find (df(x))/(dx) at x=3/4dot
