Sine, cosine, and tangent? How would I use them? And they have negatives?​
zhannawk [14.2K]

Answer: Sine - Sin

Tangent - Tan - Cosine - Cos

or inverse Cos-1 - Sin-1 - Tan-1

Step-by-step explanation:

You would use  Sine - Sin for Opposite over hypotenuse

to check it you'd use Sin-1 that is just Sine but inverse that helps you get the answer- I just learned this stuff so bare with me but all of it is the same

I'm hoping I helped give you a small clue
