The value of cos(x) is evaluated as follows: cos(x)=1- x^2/2!+ x^4/4!- x^6/6!+ x^8/8!+⋯+ x^2n/((2n)!) Where n is related to the accuracy level required for cos(x). Write a C++ program that asks the user to input n and x and then the program will evaluate cos(x) up to the 2n terms.

Marks 4 3. Find the length of the curve x t + cos t, y= t - sin t on the interval 0<t<2m. Marks 4 3. Find the length of the curve x t + cos t, y= t - sin t on the interval 0
thx!!! previous info (iv) Explain why it follows from (iv) that IV 2T+1 I(x) = Σ 2n+1 7and (2n +1)28 Like at least one of Euler's proofs, it derives the latter first and then deduces the former from it We will work with the function sin 2θ 1 + x cos 2θ ( tan-1 where T and θ are two independent variables. Sometimes we will regard x as the variable and sometimes and we will try to keep this clear....
