For the given value of s decide in which quadrant an angle o

For the given value of s, decide in which quadrant an angle of s radians lies by evaluating sin s and cos s. s = 35 A. III B. IV C. II D. I

Solution

s=35 radians=35*180/pi degree

                  = 2006.37 degree

sin s= sin (2006.37) = -.4442

cos s=cos(2006.37) = -.8959

both are negative and sin theta and cos theta are negative in third quadrant

Therefore the answer is A
