Question 845659
 Given that angle theta is in the 1st quadrant and given the point (12/13, 5/13) is on the terminal side of the angle determine the exact values of the six trigonometric functions of the real number t
------
Note: r = sqrt[(12/13)^2+(5/13)^2]
r = sqrt[169/13^2] = 1

sin(t) = y/r = 5/13
------
cos(t) = x/r = 12/13
-----
tan(t) = y/x = 5/12
