Question

1) Find the value of the trigonometric function sin (t) if sec t = -4/3 and the terminal side of angle t lies in quadrant II.
2)Find the reference angle given: -5pi/3
3) Determine the quadrant when the terminal side of the angle lies according to the following conditions: sin (t) > 0, cos (t) < 0.
4) Given the sample triangle below and the conditions a=3 and c=sqrt 51, find: cot A

Answer 1

This is the triangle for 4

Answer 2

find x using pythagoras theorem and then you can find sin(t)

Answer 3

Yeah so i get sqrt7/4.
