The point (1/3,1/4) lies on the terminal side of an angle.
Find the exact value of the six trig functions, and explain which functions are reciprocal functions to each other.

Recall that
sinθ = y/r
cosθ = x/r
tanθ = y/x
and the others are their reciprocals.
So, since
x = 1/3 = 4/12
y = 1/4 = 3/12
You have the makings of a 3-4-5 triangle, with r = 5/12
Now you can just read off the functions
sinθ = 4/5
cosθ = 3/5
tanθ = 3/4
and so on...
