Prove that the both sides of the trigonometric identity are equivalent. cos(x+y)+cos(x−y)=2cosxcosy. Trigonometric Identities Trigonometric identities are expressions that show the relationships between the trigonometric functions. Identities ar...
In trigonometry, we use the identities that are related to the trigonometric functions to simplify the mathematical expression. The trigonometric identities are the equations that are true for every value of the occurring variable...

TRIGONOMETRIC functionsStemming from an idea put forward by Loo-Keng Hua in 1962, this article describes an original way to perform arithmetic directly on infinite decimals. This approach leads to a new and elementary construction of the real number system via decimal representation. Based on the ...
