`int(dx)/(sinh^2xcosh^2x)`

Integration of trigonometric and hyperbolic functions (a) intsinh^(2) x cosh^(2) x dx, (b) int(dx)/(sinh x + 2cosh x).

int e^(x) (sinh x + cosh x) dx =

(sinh(2x))/(1+cosh(2x))=

int (2x)dx

int(dx)/(x^(2)+2x+2) =

int (sinh x )/(1+ sinh^(2)x) dx=

int(e^(x))/(cosh x+sinh x)dx

int(dx)/((a^(2)-x^(2))^(2))-(1)/(2a^(2))int(dx)/(a^(2)-x^(2))

Find the following integrals: int(dx)/(x^(2)-16) (ii) int(dx)/(sqrt(2x-x^(2)))
