The terminal side of theta lies on a given line in the specified quadrant. Find the values of the six trigonometric functions of theta by finding a point on the line.
y= 3/2x in quadrant 4

let x=2, then y = (3/2)(2) = 3
then r^2 = 2^2 + (3)^2 = 13
r = √13
sinØ = 3/√13 , cscØ = √13/3
cosØ = 2/√13 , secØ = √13/2
tanØ = 3/2 , cotØ = 2/3
