Question:
Trigonometry
Please give step-by-step answers to the following trigonometry problems.
1) Assume that the terminal side of an angle of t radians passes through the point (.9, -.4) . Find sin (t), cos (t), tan (t).
2) Assume that the terminal side of an angle of t radians in standard position lies in the given quadrant on the given straight line. Find sin (t), cos (t), tan (t). [Hint: Find a point on the terminal side of the angle.]
Quadrant III; line through the origin parallel to 7x - 3y = -9.
