Assume that ? is an acute angle in a right triangle satisfying the given condition. Evaluate the remaining trigonometric functions.
Find:
Cos:
Tan:
Sec:
Cot:
Solution
csc theta= 22/ 9
and sin theta=1/csc theta
sin theta= 9/22
so opposite= 9 and hypotenuse=22
therefore adjacent =sqrt(22^2 - 9^2)= sqrt 403
cos theta= adjacent/hypotenuse= sqrt 403/22
tan theta= opposite/adjacent= 9/sqrt403=9sqrt403/403
sec theta= 1/cos theta=22/sqrt403=22sqrt403/403
cot theta=1/tan theta= sqrt403/9
