Question

What is the relationship between the Unit Circle and the graphs of Sine, Cosine, and Tangent?

Answer 1

the range of this functions,sin,cos,tan is (-1,1). If you take the projection of a radius of this sircle on the x-axis as the value of the cos a, and the projection of a radius of this sircle on the y-axis as the value of the sin a where a is angle that this radius forms with x-axis you get all the possible values.

Answer 2

sry, tan range is (-infinity, infinity)
