Question 756291: sin310degree
i need help writing as a trig function using reference angle
Answer by algebraic penguin(13)   (Show Source):
You can put this solution on YOUR website! Hello,
If you are writing a trig function using a reference angle, you write in this form: sin(310o). The o stands for a degree sign. A degree sign is basically an o superscripted.
If you are using radians, then you write it in terms of pi. Note that 180 degrees is 1 radian, which is represented using the pi symbol. sin(310o)=sin((31/18)pi)
