🐈 Sin Cos Tan Rules

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. Check Trigonometry Formulas to get formulas related to trigonometry. Table of Contents: Definition List of Trig Functions Reciprocal Identities \(\sin{x} = \frac{o}{h}\), \(\cos{x} = \frac{a}{h}\) and \(\tan{x} = \frac{o}{a}\) Or: \(s^o_h~c^a_h~t^o_a\). Accurate trigonometric ratios for 0°, 30°, 45°, 60° and 90° Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. They are often written as sin (x), cos (x), and tan (x), where x is an angle in radians or degrees. Created by Sal Khan.
