Step 1:
\The trigonometric function is , where
lies in quadrant II.
Right angled triangle definition of trigonometric function
Opposite side = 3 and hypotenuse = 5.
\Pythagorean theorem:
\For right angled triangle, square of Hypotenuse is equal to sum of squares of other two sides.
\Substitute opposite side = 3 and hypotenuse = 5 in above theorem.
\Adjacent side = 4.
\Sine and Cosecant functions are positive and remaining trigonometric functions are negative.
\Since, lies in quadrant II.
