Find the five remaining trigonometic functions of theta sec
Find the five remaining trigonometic functions of
theta.
sec (theta) = 6/5, sin theta < 0
sin =?
cos=?
Tan=?
Csc=?
Cot=?
Sec=6/5
Solution
sec theta=6/5
cos theta=1/sec theta=5/6
Here adjacent=5 and hypotenuse=6
Therefore opposite=sqrt(6^2 - 5^2)=sqrt11
and sin theta is negative
sin theta=opposite/hypotenuse=- sqrt11/6
csc theta= 1/sin theta= -6/sqrt11= -6sqrt11/11
tan theta=sin theta/cos theta= -sqrt11/5
cot theta=1/tan theta= -5/sqrt11=-5sqrt11/11
