9 hours ago List of trigonometric identities 2 Trigonometric functions The primary trigonometric functions are the sine and cosine of an angle. These are sometimes abbreviated sin(θ) andcos(θ), respectively, where θ is the angle, but the parentheses around the angle are often omitted, e.g., sin θ andcos θ. The tangent (tan) of an angle is the ratio of the sine to the cosine:

8 hours ago TRIGONOMETRIC FORMULAS Basic Identities The functions cos(θ) and sin(θ) are defined to be the x and y coordinates of the point at an angle of θ on the unit circle. Therefore, sin(−θ) = −sin(θ), cos(−θ) = cos(θ), and sin2(θ) + cos2(θ) = 1. The other trigonometric functions are defined in terms of sine and cosine:

What are the trigonometric identities?
In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. ... They are distinct from triangle identities, which are identities potentially involving angles but also involving side lengths or other lengths of a triangle.
What are the six trigonometry functions?
The six main trigonometric functions are sine, cosine, tangent, secant, cosecant, and cotangent. They are useful for finding heights and distances, and have practical applications in many fields including architecture, surveying, and engineering.
What is the formula for trigonometry?
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x3 − 3x + d = 0, where x is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
