Trigonometric functions and their reciprocals on the unit circle. All of the right-angled triangles are similar, i.e. the ratios between their corresponding sides are the same. For sin, cos and tan the unit-length radius forms the hypotenuse of the triangle that defines them. 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.

Solving for an angle in a right triangle using the trigonometric ratios Sine and cosine of complementary angles Modeling with right triangles The reciprocal trigonometric ratios Unit 2: Trigonometric functions 0/1900 Mastery points We know that sin, cos, and tan are the reciprocals of cosec (or csc), sec, and cot functions. Thus, we can derive 3 more formulas related to sin, cos, and tan. sin A = 1/csc A (or) csc A = 1/ sin A. cos A = 1/sec A (or) sec A = 1/cos A. tan A = 1/cot A (or) cot A = 1/tan A. Learn how to calculate sine, cosine and tangent of any angle using a right-angled triangle. See examples, formulas, graphs and exercises to practice the functions. Find out the difference between sine, cosine and tangent, and the other functions such as secant, cosecant and cotangent.
