What are Trigonometric Ratios?
Trigonometric Ratios are the ratio of sides of a right angled triangle for the specific angle. The sides adjacent to the assumed angle θ are hypotenuse and the base. Hypotenuse is the longest side of the right triangle while the other side is the base. There are six trigonometric ratios namely sin, cos, tan, cot, sec and cosec. The expression of these ratio in terms of sides of right triangle for a given angle θ is mentioned below:
- Sin θ = Perpendicular/Hypotenuse
- Cos θ = Base/Hypotenuse
- Tan θ = Perpendicular/Base
- Cot θ = Base/Perpendicular
- Sec θ = Hypotenuse/Base
- Cosec θ = Hypotenuse/Perpendicular
Cos 0 Degrees
Cos 0 is equal to 1. Cosine Ratio in Trigonometry is defined as the ratio of the base to the hypotenuse. In Trigonometry, the angle θ is between the base and the hypotenuse of the right-angled triangle. Cosine Ratio is one of six ratios used in trigonometry. Trigonometric Ratios are the ratio of two sides of a triangle calculated for a given angle. Trigonometry is made up of two words trigono and metron where trigono means in triangle and metron means to measure the angles.
