The Maclaurin series expansion for cosx is cosx=1x2/2+x4/4!x6/6!+x8/8!+ starting with the simplest version, cosx, add terms one at a time to estimate cos(pi/4). After each new term is added, compute the true and approximate percent relative errors. Use your calculator to find the true value. Add terms until the absolute value of the approximate error estimate falls below an error criterion conforming to two significant figures.

Note(it has to be in python)
