To build speed, try calculating the derivatives on the first sheet mentally … and have a friend or parent check your answers. If you are a teacher, please note that the sheets have been designed so that they may be laminated back-to-back (questions on one side and answers on the other) and used in a classroom setting.

derivative of e t, don’t forget to use the chain rule. Answer. 20. Hint. arctan(3x 5). The arctangent func-tion is also denoted tan 1, but that notation sug-gests that tan 1 xshould be the same as 1=tanx, which it isn’t. The notation arctan is unambiguous.

Let us first make it clear what numerical differentiation is. Problem 11.1 (Numerical differentiation). Let f be a given function that is only known at a number of isolated points. The problem of numerical differ-entiation is to compute an approximation to the derivative f 0 of f by suitable combinations of the known values of f.
