Consider the following function, which you linearized in the preceding exercise.

g(x)=cos^2x+cosx

Having linearized the function about x=/2, calculate the difference between the real expression gg and the linearized approximation g g^. Store your result in a variable lindiff, which should be a sympy expression.

You should remove the spurious O term by calling the method removeO() on the result of the linearization. Also keep in mind that series accepts anumber of terms, not anorder, so you'll need to think about whatlinearizesthe function (makes it only a function of x)
