Question

Fan and medal:

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 - 9y = -2.

Answer 1

Answer 2

The point where the line through the origin intersects the unit circle , is the coordinate :

\[(x,y) = (\cos(\theta), \sin(\theta))\]

Answer 3

And
\[\tan(\theta) = \frac{ y }{ x } = \frac{ \sin(\theta) }{ \cos(\theta) }\]
