This week in math 10 got ourselves into a new unit called trigonometry. In trig we use 3 new buttons on our calculators, Cosine, Sine, and Tangent. You use all 3 buttons on your calculator to help you solve right angled triangles, something you need to remember to help you is a word that you need to remember, the word is SOH CAH TOA, SOH is for Sine and that its Opposite and Hypotenuse, CAH is for Cosine we use Adjacent and Hypotenuse, and for TOA its for Tangent you use Opposite and Adjacent.
