formula for sin-1X + sin-1Y , sin-1X -sin-1Y
cos-1X + cos-1Y
cos-1X - cos-1Y
find the value of x : sin-1x + sin-1(1-x) = cos-1x
Find distance of the point (-2,3,-4) from the line (x+2)/3=(2y+3)/4=(3z+4)/5, measured parallel to the plane 4x+12y-3z+1=0
Find the equation of the plane containing the lines--
r = i + j + u(i + 2j - k) and r = i + j + k(-i + j - 2k)
Find the distance of this plane from the origin and also from the point (1,1,1)
integrate : 1/sin^4x+cos^4x dx
find the derivative of cos root x wrt x from first principle??
2tan^-1x = cos^-1(1-x^2/1+x^2)
how to integrate
f (log(sin x ))dx
if y= [log(x+root x2+1)]2 show that (1+x2) d2y/dx2 +xdy/dx =2
integration of root Tan x
