I need this in matlab please

Thanks

A series expansion for sin(x) is given by sin(x) = x - x^3/3! + x^5/5! - x^7/7! + ... a) Write a Matlab script to calculate sin (pi/3) using this series expansion. Ensure that the script will add terms one at a time until the numerical result is accurate to 4 significant figures. b) Plot the exact analytical form of sin(x) for 0
