Use a calculator to evaluate each function Round your answer

Use a calculator to evaluate each function. Round your answers to four decimal places. (Be sure the calculator In the correct mode.)

Keep calculator in radians if you are using pi/12 or in degrees if u are using 360/12

15. (a) cot(pi/12) = 3.7321

15. (b) tan(pi/12) = 0.2679

16. (a) it is in radians. do not confuse with degrees

csc(1) = 1.18839

16. (b) tam(1/3) = 0.34625
