This value of x is our “b” value. Take the derivative of f (x) and substitute it into the formula as seen above. Plug our “b” value from step 1 into our formula from step 2 and simplify. Example WebMay 22, 2024 · “Differentiation rules” can be developed that allow us to compute all the partial derivatives at once, taking advantage of the matrix forms of the functions. As you will see, these rules are mostly ‘organizational’ and seldom go beyond differentiation of linear expressions or squares. We cover here only the most basic ones. cinemas in cp
