There are multiple formulas regarding the product, the quotient, addition and subtraction of angles. I have a textbook that states that as long as you understand the sum of angles, it's really all you need to know. I'm going with that textbook and going to show just two identities.")

Later on comes the idea of sine, cosine and tangent. There is a question that is left unanswered until we learn the definitions of sine, cosine and tangent. The question is: we know that a ramp can be harder to walk on according to how much inclined it is, with flat being zero angle and 90° the hardest. Is there a relationship of how many units we walk forwards and how many units we go up...")
