Ever heard of CAST?

I have not

Answer 5

But I was thinking if tan = sin/cos then sin and cos were are not negative

Answer 6

or they are both negative or both positive?

Answer 7

It's like a quick way to see where the ratios are positive and negative, A represents all positive in that quadrant, S is sin theta, C is cos theta, and T is tan theta. So they are positive in those quadrants where the letter is, and negative in the rest.

Answer 8

so it would be the 3rd quadrant then?

Answer 9

since Tan is positive in quadrant 3 ?
