using matlab... help please

2- The Maclaurin series expansion for cos x is x2 x4 x6 x8 2 4 6! 8! Starting with the simplest version, cos x = 1, add terms one at a time to estimate cos(t/6). After each new term is added, compute the true and approximate percent relative errors. Add terms until the absolute value of the approximate pervent relativ error estimate falls below 0.01%. 2- The Maclaurin series expansion for cos x is x2 x4 x6 x8 2 4 6! 8!
