Step-by-step explanation:
To do this, we must use the unit circle. At the angle the coordinate pair is (
,
) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan =
And the other functions would be the reciprocal of these
csc =
sec =
cot =
This would mean that
sinx =
cosx =
tanx = or
if you're supposed to rationalize your denominators
cscx = 2
secx = or
cot =
