how we cancel sin by arcsin?
and also arcsin is not the reciprocal of sin...
You cannot cancel sin-1x and sinx , as both are not reciprocal of each other .
If you have sin-1(sinx) , then it is equal to x . Vice versa is also true.
Here suppose x = 45 , then sin45 = 1/(2)1/2 , and sin-1(1/(2)1/2 ) = pi/4
So here first find sinx and then find its inverse .
