The point P in the figure below has y-coordinate 40/41. Can you help me find Sin(t), cos(t), tan(t), and sec(t) from the unit circle?

You didn't iclude the figure.....need to know if the point given is in Q I or Q II

Here is a good start.

From your desctiption there are 2 possible point T's

See if you can work out what i have done and finish it for yourself.
