How would I find sin, cos, and tangent with points in a unit circle?
The unit circle is a circle with a radius of 1.
Then, we know that the equation of the unit circle is:
`x^2 + y^2 =` 1
Let us assume that;
sin(t) = x
cos(t) = y
==> `sin^2 t + cos^2 t = ` 1
So, if we are given the point (1,0) is on the unit circle then we know that:
sin(t) = x = 1
cos(t) = y = 0
Then we conclude that the angle t= `pi/2 + 2kpi`
