Week 16 – Pre Calc 11 – Trig Ratios

This week in pre calc 11 we were learning about trigonometry and the 3 ratios for right angle triangles (sine, cosine, and tangent) and their associated acronyms relating to their respective equations SOH CAH TOA for sin Θ = cos Θ and tan Θ and how to use those to solve for missing sides of a triangle.

For example i was given the adjacent side and the opposite side and needed to find the angle facing the opposite side and decided to use tan ratio, the mistake i made by doing so was using the tan ratio but instead of  i put it in as which gave me a completely different answer and one that involved me accidentally making up a fourth trig ratio

it is important to know for certain what your trig ratios are because they are the basic building blocks of everything to do with trigonometry and if you get those wrong you will be hopelessly lost in trig
