By using Matlab

1. The Taylor's series expansion of cos(x) is 4 cos(x)-1-2, +?--+-..DX 2n (2n)! where x is in radians. Write a user-defined function that determines cos(x) using Taylor's series expansion. For function name and arguments use yecosTaylor(x), where the input argument x is the angle in degrees and the output argument y is the value for cos(x). In the program use a loop for adding the terms of the Taylor's series. If an is the nth term in the series, then the sum Sn of the n terms is Sn Sn1tan. In each pass, calculate the estimated error E given by the equation: SnSn-1 n-1 Stop adding terms when E s 0.000001. Use cosTaylor for calculating a) cos(60) b) cos(110)
