Explain how the unit circle can be used to find sin θ,cosθ,and tan θ for any central angle θ (positive or negative).What are the values of these functions in general?

Question

Do you know what the center and radius is of the unit circle is?

freckles · Answer

If so try drawing that circle on the cartesian plane, and then draw a triangle with hyp beginning at (0,0) and ending at some point (x,y) in the 1st quadrant

freckles · Answer

Then we will labeled the central angle contained in that triangle as theta

freckles · Answer

and then you can find cos(theta), sin(theta), tan(theta), and so on...
