1) d(arcsin(y))/dx= 1/sqrt[1-y^2] (dy/dx)
2) d(arcsin(xy))/dx= 1/sqrt[1-(xy)^2] (d(xy)/dx)
Prove that
Given that the variables x and y satisfy the equation
find when x=y=0
I have done the first part, proving .
I don't know how to do this second part. Differentiating arcsinx I know how, but arcsiny and arcsin(xy) I don't know what to do. Any pointers?
Thanks
