What I know about Sine, Cosine, and Tangent so far…

What is Sine, Cosine, and Tangent?

They are 3 fundamental ratios of trigonometry. Each of these is a ratio of two sides of a right triangle.

I know so far that:

sine= opposite/hypotenuse.

cos= adjacent/hypotenuse

tan=opposite/adjacent

Using sine, cosine, and tangent, we can find the ratio of the triangle

If we do the inverse, than we can find the angle of the triangle.

I now know what the sign means on my calculator and I know how and why we use these signs.
