Question 756882: A diagram is needed please i need to understand this .I am having a hard time.
1.)If P(-5/13,12/13) is on the point on the unit circle corresponding to the real number t, determine the coordinates of
i)P(t-3pie)
ii)P(-t+pie)

2.)If P(t)=(7/25,24/25) be the point on the unit circle that corresponds to t.
Find P(t-pie).Is it -7/25,24/25?

Angle AOP, swept counterclockwise from OA to OP corresponds to
Maybe is the measure of AOP, or the measure of AOP plus a number of whole turns.
An angle measuring would be one whole counterclockwise turn.
An angle measuring would be half of a counterclockwise turn.
An angle measuring would be half of a clockwise turn.

i. Adding or subtracting to angle would take you to point Q, halfway across the circle.

Adding or subtracting would take you a full turn back to the same spot.

ii. A minus sign as in means go in the opposite direction, so .
Then, adding would take you halfway around the circle to

2. If P(t)=(7/25,24/25), P(t-pi) is halfway across the circle at a point
