What am I doing wrong?
y=sinx
=1/(sinx)^-1
dy/dx = 1/(-1*(sinx)^-2)*cosx
=-(sinx)^2/cosx
dy/dx of sinx = cosx
How is cosx equal to -(sinx)^2/cosx? Is it equal to it? Cuz I been trying for like an hour, and it just doesn't make sense! I dont see that I did anything wrong. And it is just basic math..
