Learning Pythagorean Identities

Let us learn about Pythagorean Identities
In a unit circle, the study shows that a point on the unit circle (the vertex of the right triangle) can be represented by the coordinates (cos Θ, sin Θ).


Since the bases of a right triangle in the unit circle have the values of sinΘ and cosΘ, the Pythagorean Theorem can be used to obtain, also get information on pythagorean theorem word problems


sin²Θ + cos²Θ = 1


This equation is called as Pythagorean identity. Here the value of theta in immaterial.
