The Pythagorean theorem also Solve mathematic problem math is all about solving problems, and there's no better feeling than finding the right answer. Supply multiple methods WebThe trigonometric identities are derived from the Pythagorean theorem: { {\sin}^2} (\theta)+ { {\cos}^2} (\theta)=1 sin2(θ) + cos2(θ) = 1 This is the most important Pythagorean identity. This identity is true for all values of θ. Using this first identity, we can create two additional Pythagorean identities:
