tan^(2)x-sin^(2)x=tan^(2)x sin^(2)x

int(sin^(2)x*sec^(2)x+2tan x*sin^(-1)x*sqrt(1-x^(2)))/(sqrt(1-x^(2))(1+tan^(2)x))dx

sin (tan ^(-1)2x)

sin (tan ^(-1)2x)

If sin(x+y).sec(x-y)=1 then tan^(2)x+sin^(2)x+sec^(2)x=?

The common roots of the equations 2 sin^(2) x + sin ^(2)2 x = 2 and sin 2 x + cos 2 x = tan x is

Show that cos 2 x=cos ^(2) x-sin ^(2) x=2 cos ^(2) x-1=1-2 sin ^(2) x=(1-tan ^(2) x)/(1+tan ^(2) x)

Simplify 2"tan"^(-1)x+"sin"^(-1)((2x)/(1+x^(2))) in terms of "tan"^(-1)x .

Solve for x:2tan^(-1)(sin x)=tan^(-1)(2sec x),x!=(pi)/(2)
