how do I use the cos sin and tan
You use cos (cosign) sin (sine) and tan (tangent) to find the lengths of sides of triangles.
Also, you press these buttons on a calculator to use them:
Sine is \(\frac{opposite}{hypotenuse}\)
Cosine is \(\frac{adjacent}{hypotenuse}\)
Tangent is \(\frac{opposite}{hypotenuse}\)
