1. ## trigonometic funtions

how do you Find the exact values of the six trigonometric functions of a
120 ° angle

how do you Find the measurement of the reference angle of an angle measuring 7 π /4

If you are Given that sin θ = -1/2 for an angle in Quadrant III how do you find the exact value of sec θ

how do you Find the values of the six trigonometric functions of the angle in standard position with the terminal side passing through the point P(-4, 3)

2. Remember that Sin = Opp/Hyp, Cos = Adj/Hyp and Tan = Opp/Adj

Then use pythagorean triples to give you the exact values.

wat is pythagorean triples andhow do i get the opp the hp and the adj

4. For example, you know that Sin120 = Sin 60

In the right-angled triangle with a 60 degree angle, the sides are 1, 2 and root 3.

Opposite the 60 degree angle is the root 3 side and the hypoteneuse is 2.

So as Sin = Opp/Hyp, Sin 60 = root(3)/2
