The derivative of is , that is, times the derivative of , a result dictated by the Chain rule. For , the "outer" function is , whose derivative is one over the "inner" function, again . This must be multiplied by the derivative of the inner function, which is then .
The reader should feel free to implement this differentiation in the
tutor.
