Plot the point given. Use the distance formula to calculate the measure of the line segment from the origin to the point to get the measure of the hypotenuse (or recognize 3, 4, 5 as a Pythagorean Triple).
Then sine is opposite divided by hypotenuse, cosine is adjacent divided by hypotenuse, tangent is sine over cosine, cosecant is the reciprocal of sine, secant is the reciprocal of cosine, and cotangent is the reciprocal of tangent.

***
Given coordinates places θ in Q2 where sin>0, cos<0, tan<0.
We are working with a (3-4-5) reference right triangle.
sin θ=3/5
cos θ=-4/5
tan θ=-3/4
csc θ=5/3
sec θ=-5/4
cot θ=-4/3
