Question 1099273: Find the exact values for Sin(theta), Cos(theta), Tan(theta). using the information given..
Sin(2theta) = 24/25; 2theta in QII.
I have tried using a Double Angle Identity for Sine, Cosine, and Tangent but I am not anywhere near the answer, I am confused on exactly what I should do..
Thanks in advance.

Using the projections of = rotaing vector
( projection on the horizontal axis )
( negative because is in 2nd quadrant )
---------------------------------------------
The angle theta will be in the 1st quadrant where all
trig functions are positive
----------------------------------
I'll use 1/2 angle formulas
( sin is positive in 1st quadrant )
---------------------------------------------------
( cos is positive in 1st quadrant )
------------------------------
The answer should be You can finish
