Question

what is compound angle formula for cosec(x+y)= ​

Answer 1

Answer:

A compound angle formula or addition formula is a trigonometric identity which expresses a trigonometric function of (A+B) or (A−B) in terms of trigonometric functions of A and B. The three basic formulae are: cos(A±B)=cosAcosB∓sinAsinBsin(A±B)=sinAcosB±cosAsinBtan(A±B)=tanA±tanB1∓tanAtanB.
