Homework SourseGiven that sin pi16 01951 and cos pi16 09808 use these app
Given that sin (pi/16) = 0.1951 and cos (pi/16) = 0.9808, use these approximate function values to find a) the other four function values for pi/16 and b) the six function values for 7pi/16
Given that sin (pi/16) = 0.1951 and cos (pi/16) = 0.9808, use these approximate function values to find a) the other four function values for pi/16 and b) the six function values for 7pi/16
Solution
sin (pi/16) = 0.1951
cos (pi/16) = 0.9808
tan (pi/16) = sin (pi/16) / cos ((pi/16) = 0.1989
cot (pi/16) = cos (pi/16) / sin ((pi/16) = 5.0272
sec (pi/16) = 1 / cos ((pi/16) = 1.0196
csc (pi/16) = 1 / sin ((pi/16) = 5.1256
7pi/16 answers
sin (7pi/16) = cos(pi/2 - 7pi/16) = 0.9808
cos (7pi/16) = sin(pi/2 - 7pi/16) = 0.1951
tan (7pi/16) = cot(pi/2 - 7pi/16) = 5.0272
cot (7pi/16) = tan(pi/2 - 7pi/16) = 0.1989
sec (7pi/16) = csc(pi/2 - 7pi/16) = 5.1256
csc (7pi/16) = sec(pi/2 - 7pi/16) = 1.0196
