Section 4.3
Let me see.
I need to find the coordinates of the point (x, y).
To find the x-coordinate, do this:
x = 10•cos (20°)
To find the y-coordinate, do this:
y = 10• sin (20°)
After finding the values of x and y, I can then find the six trigonometric functions of a 20 degree angle by using SOHCAOTOA.
Yes?
