What Is Cos Over Cos Sine cosine and tangent are the primary trigonometry functions whereas cotangent secant and cosecant are the other three functions The trigonometric identities are based on all the six trig functions
Sine Cosine and Tangent Sine Cosine and Tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle For a given angle each ratio stays the same no matter how big or small the triangle is To calculate them Divide the 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
