The given trigonometric function
and
terminates in QI.
terminates in QIV, than cos
, sec
are positive and remaining trigonometric functions are negative.
The ratio of
, So x = 24 and r = 25.
The distance formula from the origin to (x, y):
.
(Squaring on each side and eliminate the square roots)
(Substitute x = 24 and r = 25)

(Subtract 576 from each side)


,
terminates in quadrant I, know any point on its terminal side.
So, x-coordinate is a negative, than
.
The six trigonometric functions using the values x = 24,
