Find the derivative of sec |
| Answer» OND derivative of an implicit FUNCTION can be found using sequential differentiation of the initial equation F(x,y)=0. At the first STEP, we get the first derivative in the FORM y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y). | |
