Lists the basic trigonometric identities, and specifies the set of trig identities to keep track of, as being the most useful ones for calculus.
The Trigonometric Identities are equations that are true for Right Angled Triangles. (If it is not a Right Angled Triangle go to the Triangle Identities page.).
You have seen quite a few trigonometric identities in the past few pages. It is convenient to have a summary of them for reference. These identities mostly refer to ...
Rewrite trigonometric expressions using the Pythagorean identity and other trigonometric identities.
Look up AND understand all your favorite trig identities.
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/ ...
Trigonometric identities are used to manipulate trigonometry equations in ... The six trig functions are sine, cosine, tangent, cosecant, secant, and cotangent.
