TRIGONOMETRIC FUNCTIONS Definitions of trig ratios and functions In Trigonometry there are six trigonometric ratios that relate the angle measures of a right triangle to the length of its sides. (Remember a right triangle contains a 90° angle) A right triangle can be formed from an initial side x and a terminal side r, where r
Recall the definitions of the trigonometric functions. The following indefinite integrals involve all of these well-known trigonometric functions. Some of the following trigonometry identities may be needed. Trigonometric Identities. Some relations between trigonometric functions are an immediate consequence of the definitions, such as cos 2 x + sin 2 x = 1, but many are not quite so easy to derive, though very useful. Although I know most of them, I usually look them up in a reference in case I don't remember correctly. The two limits from the left and from the right are different, therefore the above limit does not exist. lim x→0 sin | x | / x does not exist Example 6 Find the limit lim x→0 x / tan x Solution to Example 6: We first use the trigonometric identity tan x = sin x / cos x = -1 lim x→0 x / tan x = lim x→0 x / (sin x / cos x)

Examples using Inverse trigonometric functions Identities & Equations – Pythagorean Type sin²x + cos²x ≡1 , 1 + tan²x ≡ sec²x , 1 + cot²x ≡ cosec²x Trigonometric Identities. Some relations between trigonometric functions are an immediate consequence of the definitions, such as cos 2 x + sin 2 x = 1, but many are not quite so easy to derive, though very useful. Although I know most of them, I usually look them up in a reference in case I don't remember correctly.
It's A Fundamental Limit . The limit in Eq. [3.1] is classified as a fundamental trigonometric limit. The reason is that it's, well, fundamental, or basic, in the development of the calculus for trigonometric functions. As we'll see, the derivatives of trigonometric functions, among other things, are obtained by using this limit. Remark 3.1
You can use these properties to evaluate many limit problems involving the six basic trigonometric functions. Example 1: Evaluate . Substituting 0 for x, you find that cos x approaches 1 and sin x − 3 approaches −3; hence,. Example 2: Evaluate Because cot x = cos x/sin x, you find The numerator approaches 1 and the denominator approaches 0 through positive values because we are approaching ...This lesson on Limits of Trig Functions is designed for AP Calculus AB, BC, Calculus Honors, or College Calculus 1.

Figure %: The signs of the functions in the four quadrants Values of Quadrantal Angles When an angle lies along an axis, the values of the trigonometric functions are either 0, 1, -1, or undefined. When the value of a trigonometric function is undefined, it means that the ratio for that given function involved division by zero.
