• Trigonometric Functions. Arbitrary angles and the unit circle. We've used the unit circle to define the trigonometric functions for acute angles so far. We'll need more than acute angles in the next section where we'll look at oblique triangles. — “Trigonometric Functions”, clarku.edu
• In calculus and all its applications, the trigonometric identities are of central importance. These are called Pythagorean identities, because, as we will see in their proof, they are the trigonometric version of the Pythagorean theorem. — “Trigonometric identities”,
• true precisely when a = ±b. The formulas or trigonometric identities introduced in Such identities can be used to simpliﬂy complicated trigonometric expressions. — “LESSON 6: TRIGONOMETRIC IDENTITIES by Thomas E. Price Directory”, math.uakron.edu
• The European Space Agency 's INTErnational Gamma-Ray Astrophysics Laboratory ( INTEGRAL) is detecting some of the most energetic radiation that comes from space In Mathematics, trigonometric substitution is the substitution of trigonometric functions for other expressions. — “List of trigonometric identities - Citizendia”,
• Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle. All of the trigonometric functions of an angle θ can be constructed. — “Trigonometric functions”, schools-
• trigonometric function n. A function of an angle expressed as the ratio of two of the sides of a right triangle that contains that angle; the sine,. — “trigonometric function: Definition from ”,
• Trigonometric Identities. sin 2 + cos 2 = 1. tan 2 + 1 = sec2 cos 2A = cos 2 A - sin 2 A. cos 2A = 2cos 2 A - 1. cos 2A = 1 - 2sin 2 A. sin 2A = 2sinAcosA. — “TRIGONOMETRIC”,
• The following indefinite integrals involve all of these well-known trigonometric functions. It is assumed that you are familiar with the following rules of differentiation. These lead directly to the following indefinite. — “Trigonometric Integrals”, math.ucdavis.edu
• Calculating the final position of the astronaut at the end of the arm requires repeated use of the trigonometric functions of those angles. All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. — “Trigonometry - New World Encyclopedia”,
• In mathematics, the trigonometric functions are functions of an angle important when In order to define the trigonometric functions for the angle A, start with an arbitrary. — “Trigonometric function - Wikinfo”,
• The right triangle is important to understand because it allows us to define set of so called trigonometric functions. The Trigonometric Functions and the Circle. In the section on Angles. — “Trig 2”, lasp.colorado.edu
• The trigonometric functions are most simply defined using the unit circle. As a result of this definition, the trigonometric functions are periodic with period , so. — “Trigonometry -- from Wolfram MathWorld”,
• 3. Derivatives of Trigonometric Functions. We shall start by giving derivative of f(x) = sin x, and then using it to obtain the derivatives of the other five trigonometric functions. — “Derivatives of Trigonometric Functions”, people.hofstra.edu
• Math2.org Math Tables: Trigonometric Identities (Math) sin(theta) = a / c. csc(theta) = 1 / sin(theta) = c / a. cos(theta) = b / c. sec(theta) = 1 / cos(theta) = c / b. tan(theta) = sin(theta) / cos(theta) = a / b. cot(theta) = 1/ tan(theta) = b / a. sin(-x) = -sin(x) csc(-x) = -csc(x). — “Trigonometric Indentities”, math2.org

• TRIGONOMETRIC FUNCTIONS. Recall that a real number can be interpreted as the measure of the angle constructed as follows: wrap a piece of string of length units around the unit circle (counterclockwise if , clockwise if ) with initial point P(1,0) and terminal point Q(x,y). — “Trigonometric Functions”,
• In mathematics, the trigonometric functions are functions of an angle; they are important when studying Above, only sine and cosine were defined directly by the unit circle, but the other four trigonometric functions can be defined by:. — “Trigonometric function - encyclopedia article - Citizendium”,
• Trigonometric function - Definition. In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. Trigonometric functions specify the relationships between side lengths and interior angles of a right triangle. — “Trigonometric function - Definition”,
• The paper considers the volume formula, as well as trigonometric identities,that hold for a tetrahedron in 3-dimensional spherical space which posses acertain symmetry. In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for. — “Trigonometric Identities - Kosmix : Reference, Videos, Images”,
• Trigonometry defines the trigonometric functions, which describe those relationships and have applicability Trigonometric functions were among the earliest uses for mathematical tables. Such tables were incorporated into mathematics textbooks and students were taught to look up values and how to. — “Trigonometry - Wikipedia, the free encyclopedia”,
