Use the given information to find the values of the remainin
Use the given information to find the values of the remaining five trigonometric functions. (Enter your answers in exact form.)
tan x = 8, pie/2 <x < pie
Solution
tanx=-8
x lies in second quadrant
here opposite=8 and adjacent =1
Therefore hypotenuse=sqrt(8^2 + 1^2)=sqrt65
And in second quadrant sine and csc are positive and all others are negative
sin theta=opposite/hypotenuse
sinx=8/sqrt65=8sqrt65/65
csc theta=1/sin theta
csc x= sqrt65/8
cos theta=adjacent/hypotenuse
cos x=-1/sqrt65=-sqrt65/65
sec theta=1/cos theta
sec x=1/cos x=-sqrt 65
cot theta= 1/tan theta
cot x= -1/8
