Question 805437: Determine the values of the trigonometric functions of t if P(t) lies in the second quadrant and on the line
y = −3x.
How do I find the values of sin(t), cos(t), tan(t), cot(t), sec(t), and csc(t)?
Thank you for your help!

Determine the values of the trigonometric functions of t if P(t) lies in the second quadrant and on the line
y = −3x.
-------
slope = -3
slope = tangent = y/x = -3/1 = 3/-1
So y = 3 and x = -1
----
Therefore r = sqrt(3^2+1^2) = sqrt(10)
-------
How do I find the values of sin(t), cos(t), tan(t), cot(t), sec(t), and csc(t)?
-----
sin(t) = y/r = 3/sqrt(10)
cos(t) = x/r = -1/sqrt(10)
tan(t) = y/x = -3
csc(t) = sqrt(10)/3
sec(t) = -sqrt(10)
cot(t) = x/y = -1/3
