Web1 dec. 2024 · The main Pythagorean identities are: \sin^2(θ) + \cos^2(θ) = 1 \\ 1 + \tan^2(θ) = \sec^2(θ) \\ 1 + \cot^2(θ) = \csc^2(θ) The Pythagorean identities are … WebIn trigonometry, reciprocal identities are sometimes called inverse identities. Reciprocal identities are inverse sine, cosine, and tangent functions written as “arc” prefixes such as arcsine, arccosine, and arctan. For instance, functions like sin^-1 (x) and cos^-1 (x) are inverse identities. Either notation is correct and acceptable.
WebThe Pythagorean Identities are interesting relationships between trigonometric ratios. The Pythagorean Theorem leads to a simple proof of the Pythagorean Identities using only the basic definitions of trig functions. The Pythagorean Theorem on a right triangle with legs a,b and hypotenuse c gives us: a2+b2=c2.
