Question

Trigonometric formulas

Answer 1

Formulas for right triangles. ... If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side.

Answer 2

The six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. So now all the trigonometricratios are based on the lengths of these lengths of the side of the triangle and the angle of the triangle. The basic trigonometric identities based on the Pythagoras Theorem are listed here.
