Document Summary
110: you are not permitted to use a calculator on this exam, in order to receive full credit, you must show your work. Be wary of doing computations in your head. Fall-2016 (a) (5 points) find the exact value of tan(180 ). (b) (5 points) find the value of. 4 sin(33 ) csc(33 ) 7 sec(58 ) cos(58 ). (c) (10 points) find the exact value of sin(990 ). 2 (20 points) determine the amplitude, period, and phase shift of y = 1 graph the function (you should graph the function for more than one period). Fall-2016 (a) (5 points) write an equation of a cosine function with amplitude is 4, period is . 2 . (b) (5 points) fnd the asymptotes of y = 2 csc(2x) on the interval [0, ]. 5 (20 points) graph the function y = 2 cot(x . 6 (10 points) the point p = ( number t. find the exact value of tan(t).
