Identities expressing trig functions in terms of their complements. Pay attention specifically of the algebraic signs of the derivatives so that you will not be confused with the signs later on. Sinth Tanth and 1 are the heights to the line starting from the x-axis while Costh 1 and Cotth are lengths along the x-axis starting from the origin.

1 a2 b2 c2 a 2 b 2 c 2. In this equation c c represents the length of the hypotenuse and a a and b b the lengths of the triangles other two sides. The theorem can be written as an equation relating the lengths of the sides a a b b and c c often called the Pythagorean equation. Note that sine cosine tangent cotangent cosecant and secant are called Trigonometric Functions that defines the relationship between the sides and angles of the triangle.
