Multiply the top variable by the derivative of the bottom variable. Subtract your result in Step 2 from your result in Step 1. Be careful, order matters! WebJun 29, 2013 · In questions having implicit functions, this expression -> "d/dx y^2" often appears in the calculation process. I use the chain rule to convert it to 2y x dy/dx. This is NOT correct! (Unless that middle "x" indicates multiplication- a very bad notation when x is also used as a variable!) The derivative "d/dx y^2" is 2y dy/dx.
