Explain how to do in mathmatica.

PART 1. Truncation error Write a function that computes the Taylor approximation of 2cos(x). Using the Manipulate environment, plot the Taylor approximation (series) of 2cos(x) along with Mathematica's 2cos(x) function. -- Allow the user to change the number of terms in the approximation between 3 and 20. The initial number of terms should be 3 . -- The summation variable should increment by I. -- Allow the user to change the domain between [-Pi, Pi] and [10Pi,10Pi], incrementing by Pi/2. -- For both sliders, add meaningful text (string) as the label instead of the variable name. -- Use PlotRange->\{-3,3\}
