Question 747509: Hi, Im stuck on this problem. The directions are: "The terminal side of an angle of t radians lies in the given quadrant on the given line. Find sin t, cos t, and tan t. "
The actual problem is : quadrant 3; line
My first thought was to graph the line and then find a point on the terminal ray and thought I could build from that. Turns out that I have no clue how to even do that. Could you help me solve this problem? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! "The terminal side of an angle of t radians lies in the given quadrant on the given line. Find sin t, cos t, and tan t. "
The actual problem is : quadrant 3; line
--------
2y-4x = 0
------
y = 2x
-----
Points for QIII:
(0,0) and (-1,-2)
---
x = -2 ; y = -1
---
Solve for "r":
r = sqrt[2^2+1^2] = sqrt(5)
-------
sin = y/r = -1/sqrt(5) = -sqrt(5)/5
----
cos = x/r = -2/sqrt(5) = -2sqrt(5)/5
----
tan = y/x = 1/2
