WebThe Pythagorean identities are a set of trigonometric identities that are based on the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. The most common Pythagorean identities are: sin²x + cos²x = 1 1 + tan²x = sec²x. 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. the carebox
