How to solve pythagorean identities
WebDec 19, 2013 · The Pythagorean identity tells us that no matter what the value of θ is, sin²θ+cos²θ is equal to 1. This follows from the Pythagorean theorem, which is why it's called the Pythagorean … 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.
