The Pythagorean identities in trigonometry are the three identities that come from the Pythagorean theorem. Recall that the Pythagorean theorem states that the hypotenuse squared of a right triangle is the sum of the square of each of the other two sides. The Pythagorean theorem.

All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Trigonometry (from Greek trigōnon, triangle and metron, measure) is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

The unit circle triangle with a hypotenuse of 1. Looking at this triangle with a hypotenuse of 1, I see that my ratio for sin (theta) is a/1, so I know that a=sin (theta). My cosine then is b/1, so b=cos (theta), and my c=1. Plugging these values into the Pythagorean theorem, I arrive at my first identity.

Right Triangle. The Trigonometric Identities are equations that are true for Right Angled Triangles. (If it is not a Right Angled Triangle go to the Triangle Identities page.) Each side of a right triangle has a name: Adjacent is always next to the angle.

Specifically, they are ratios of two sides of a right triangle and a related angle. Trigonometric functions are typically used to calculate unknown lengths or angles in a right triangle.

Introduction to trigonometry. As you see, the word itself refers to three angles - a reference to triangles. Trigonometry is primarily a branch of mathematics that deals with triangles, mostly right triangles. In particular the ratios and relationships between the triangle's sides and angles. It has two main ways of being used:

the branch of mathematics that deals with the relations between the sides and angles of plane or spherical triangles, and the calculations based on them. But I was sure in trigonometry and calculus, which I might have dodged and didn't. It signifies an enormous number of things, from pot-hooks to trigonometry.
