Trigonometry is a discipline of mathematics that studies the relationships between the lengths of the sides and angles of a right-angled triangle. Trigonometric functions, also known as goniometric functions, angle functions, or circular functions, are functions that establish the relationship between an angle to the ratio of two of the sides of a right-angled triangle. The six main trigonometric functions are sine, cosine, tangent, cotangent, secant, or cosecant. Show
As given in the above figure in a right-angled triangle:
Trigonometric FunctionsTrigonometry has 6 basic trigonometric functions, they are sine, cosine, tangent, cosecant, secant, and cotangent. Now let’s look into the trigonometric functions. The six trigonometric functions are as follows,

How do you find cos from sin?Generally, for any angle θ, cos θ = sin (90° – θ). cos θ = sin (π/2 – θ).
How do you find cos θ?It can be abbreviated as Cos(θ) and looks like this: Cos(θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right triangle).
What is cos θ equal to?The Cos θ = Adjacent / Hypotenuse.
