In standard position point (2, 3) is on the terminal side of angle θ. find the values of sine, cosine, and tangent of θ? show all work.

So the point is at (2,3)  namely x = 2, and y = 3, or one could say a = 2 and b = 3,



bearing in mind that, the hypotenuse is just the radius unit in the angle, and therefore is never negative.

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
