sin cos tan trig identities For sin cos and tan the unit length radius forms the hypotenuse of the triangle that defines them The reciprocal identities arise as ratios of sides in the triangles where this unit line is no longer the hypotenuse
When we divide Sine by Cosine we get sin cos Opposite Hypotenuse Adjacent Hypotenuse Opposite Adjacent tan So we can say tan sin cos That is our first Trigonometric Identity Cosecant Secant and Cotangent We can also divide the other way around such as Adjacent Opposite instead of Opposite Adjacent to get The main trigonometric identities are Pythagorean identities reciprocal identities sum and difference identities and double angle and half angle identities For the non right angled triangles we will have to use the sine rule and the cosine rule

We have additional identities related to the functional status of the trig ratios sin t sin t cos t cos t tan t tan t Notice in particular that sine and tangent are odd functions being symmetric about the origin while cosine is an even function being symmetric about the y axis 1 Fundamental Trigonometric Identities by M Bourne Proving out fundamental trigonometric identities and diving into uses for solving problems But before we start to prove trigonometric identities let s see where the basic identities come from
