formula for sin-1X + sin-1Y , sin-1X -sin-1Y
cos-1X + cos-1Y
cos-1X - cos-1Y
find the derivative of cos root x wrt x from first principle??
find the value of x : sin-1x + sin-1(1-x) = cos-1x
2tan^-1x = cos^-1(1-x^2/1+x^2)
how to integrate
f (log(sin x ))dx
integrate : 1/sin^4x+cos^4x dx
if y= [log(x+root x2+1)]2 show that (1+x2) d2y/dx2 +xdy/dx =2
what is the value of e raised to infinity ?
