ALL OF THEM ARE WRONG

The Maclaurin series expansion for cosx is cosx=12x2+4!x46!x6+8!x8 Starting with the one-term approximation, cosx=1, add terms one at a time to estimate cos(/3). After each new term is added, compute the true and approximate percent relative errors. Use your calculator to determine the true value. Add terms until the absolute value of the approximate error estimate falls below 0.5%. (Round the value of cos(/3) to four decimal places and the values of true and approximate errors to two decimal places.)
