Given cos()=95 and is in quadrant II and sin()=37 and 0<</2. Use sum and difference formulas to find the following:
Note: You are not allowed to use decimals in your answer.

tan(+)=

Solution

The value of cos needs to be in between -1 and 1 and same for sin. So it is not possible that cos theta=-9sqrt5 and sin theta=37.
