Basic Trig


*Sine, Cosine, Tangent ONLY work with right triangles!!!!

*regular sine, cosine, tangent find side lengths

Sine-ratio of the length of the opposite side divided by the hypotenuse.
opposite/hypotenuse

Cosine-ratio of the length of the adjacent side divided by the hypotenuse
adjacent/hypotenuse

Tangent-ratio of the length of the opposite side divided by the adjacent side
opposite/adjacent

*the arc measures of sine, cosine, and tangent find the angle measure

arcsine-ratio of the angle measure of the opposite angle measure.

arcosine-ratio of the angle measure of the adjacent angle measure.

arctangent-ration of the angle measure of the hypotenuse angle measure
