Question 1084479
Point Q(-12,-9) is on the terminal arm of a circle in standard position

a) Give exact coordinates of a point P(x,y) on the terminal arm of a unit circle
b) What is the value of tan(t) and the measure of angle t?
----
tan(t) = y/x = 3/4
--> t =~ 36.87 + 180 = 216.87 degs
====================================
a) Give exact coordinates of a point P(x,y) on the terminal arm of a unit circle
r = sqrt(s^2 + y^2) = 15
----
On a unit circle, x = -12/15 = -4/5
y = -9/15 = -3/5
--> (-4/5,-3/5)
