Sin tan cos formula11/2/2023 In Δ ABC, right-angled at B, AB = 3 cm and AC = 6 cm. Sin and Cos are basic trigonometric functions along with tan functions, in Trigonometry which is a part of Mathematics. Comment Button navigates to signup page (12 votes) Upvote. Sin Cos formulas are always based on the sides of the given right-angled triangle. We often teach using SOH-CAH-TOA and using a right triangle, so sin/cos/tan are very well known. SO let us see the sin cos formula along with the other important trigonometric ratios.īasic Trigonometric Identities for Sine and Cos And tan is opposite over adjacent, which means tan is sin/cos. There are six trigonometric ratios for the right angle triangle are Sin, Cos, Tan, Cosec, Sec, Cot which stands for Sine, Cosecant, Tangent, Cosecant, Secant respectively. Sin and Cos are basic trigonometric functions that tell about the shape of a right triangle. 2 Solved Examples Sin Cos Formula Basic trigonometric ratios Then the cosine formula is, cos x (adjacent side) / (hypotenuse), where adjacent side is the side adjacent to the angle x, and hypotenuse is the longest.
