### trigonometric functions | class 11 books

In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometricfunctions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. ... The most familiartrigonometric functions are the sine, cosine, and tangent.

What are the six basic trigonometric functions?
The 6 Trig Ratios. For any right triangle, there are six trig ratios: Sine (sin), cosine(cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Here are the formulas for these six trig ratios: Given a triangle, you should be able to identify all 6 ratios for all the angles (except the right angle).

What are basic trigonometric functions?
Six basic relations, or trigonometric functions, are defined. ... The functionsoccur in pairs—sine and cosine, tangent and cotangent, secant and cosecant—called cofunctions. In equations they are usually represented as sin, cos, tan, cot, sec, and csc.

What is one example of an odd trigonometric function?

Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it's important to know them. A function f is said to be an odd function if for any number x, f(–x) = –f(x).

What are the 6 trigonometric identities?
The six main trigonometric functions are sinecosinetangentsecantcosecant, and cotangent.

What is the difference between sin cos and tan?
The cosine (often abbreviated "cos") is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated "tan") is the ratio of the length of the side opposite the angle to the length of the side adjacent. ... TOA → tan = "opposite" / "adjacent"

What is SOH CAH TOA?
A way of remembering how to compute the sine, cosine, and tangent of an angle.SOH stands for Sine equals Opposite over Hypotenuse. CAH stands for Cosine equals Adjacent over Hypotenuse. TOA stands for Tangent equals Opposite over Adjacent.
