This question was on our practice for today and I don't even know where to start. I understand how to do it in terms of cosine and sine but I don't know how to use the sum and difference formulas of sin cos and tan with the cotangent instead of the cosine. cot(a) = −5/12 and sin(b) = 3/5 with both a and b in Quadrant II. Find the exact value of each of the following. sin(a + b) cos(a + b) tan(a + b) sin(a − b) cos(a − b) tan(a − b)
