Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
Music video. "Me Porto Bonito" on YouTube. " Me Porto Bonito " (English: "I'll Behave Nicely") is a song by Puerto Rican rapper Bad Bunny and Puerto Rican singer Chencho Corleone from the former's fifth studio album Un Verano Sin Ti (2022) featured as the fifth single, following "Callaíta", "Moscow Mule", "Tití Me Preguntó" and "Después de ...
In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is ...

Pythagorean trigonometric identity. The Pythagorean trigonometric identity, also called simply the Pythagorean identity, is an identity expressing the Pythagorean theorem in terms of trigonometric functions. Along with the sum-of-angles formulae, it is one of the basic relations between the sine and cosine functions. The identity is.
