NEED HELP ASAP, WILL GIVE BRAINLIEST Thinking about the unit circle, explain how symmetry can be used to find the coordinates of points on the unit circle for angles whose terminal sides are in quadrants ii, iii, and iv.

Considering the sign behavior of each function and the angle and its multiples.

Step-by-step explanation:

1) Firstly, look at the Unit Circle below. In the Unit Circle we can with the aid of symmetry, find angles with the same height, and also the same angle value.

2) We need to remember or get to know the behavior of the trigonometric functions, in order to know whether it is positive or negative. Let's work with the tree basic ones: sine, cosine and tangent.

3) Let's take the 60º angle, to exemplify.

Symmetric angles have the same height proportional values for their angles.

Notice that the angle of 60º ∈ Quadrant II, and 120º ∈ Quadrant II and 240º for Quadrant III and 300º for Quadrant IV as well.

We can calculate their values, considering their sign behavior each quadrant for cosine function.

Similarly, for the sine function, don't forget to consider sign behavior for each quadrant

Similarly, for sine function, don't forget to considering sign behavior for each quadrant

And finally, for the tangent function

step-by-step explanation:

f(x) = y

f(-3) = -5
