i have 2 question -
1)if cos-1(x/a)+cos-1(y/b)=d
prove that : x2/a2-2xy/ab-cosd+y2/b2=sin2d
2)solve tan(cos-1x)=sin(tan-1x)
3)tan-1x+tan-1y+tan-1z=pi/2
prove that xy+yz+zx =1
Integrate the Function Sin(x-a)/Sin(x+a)
cos[tan-1{sin(cot-1 x)}] = [(1 + x^2)/(1 - x^2)]^-1
prove it!!!!
integral [ 1/log x - 1/ (log x)2 ]dx??
If A is a square matrix of order 3 such that |adj A|=225,find |A'|
