1. The problem statement, all variables and given/known data Find an equation of the tangent line to the graph of the function f defined by the following equation at the indicated point. (x - y - 1)3 = x; (1, -1) 3. The attempt at a solution x3-y3=1 3y2(dy/dx)-3x2=0 3y2(dy/dx)=3x22 (dy/dx)=3y2/3x2 (dy/dx)=x2/y2 slope = (dy/dx) = 1 y-(-1)= 1(x-1) y=x-2 thats wrong -.- i tried making it dy/dx = x/y and still wrong. where am i messing up? I'm pretty sure it has to do with the x at the end but i have no idea what to do with it! We just learned derivatives so I'm still messing up with them.
