To find the exact values of
,
, and
for a point
on the terminal side of
, we can use the definitions of trigonometric functions in terms of the coordinates of a point on the terminal side of an angle.Step 1: Find the radius (r) using the Pythagorean theorem:
Step 2: Find
:
Step 3: Find
:
Step 4: Find
:
Therefore, the exact values are:
