You can see the Pythagorean Thereom relationship clearly if you consider the unit circle where the angle is t the opposite side is sin t y the adjacent side is cos t x and the hypotenuse is 1 We have additional identities All the trigonometric identities are based on the six trigonometric ratios They are sine cosine tangent cosecant secant and cotangent All these trigonometric ratios are defined using the sides of the right triangle such as an adjacent
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse Sin Opposite side Hypotenuse Cos Adjacent side Hypotenuse How do you verify sin x cos x 2sin 2 x 1 sin x cos x How do you verify sinx cosx tanxsinx secx cos x tan x How do you simplify sin 2 t cos 2 t cos 2 t
