Here are addition theorems satisfied by the lemniscate sine sl and the lemniscate cosine cl. Addition theorems for sinp and friends are harder to come by. In [1] the authors say “no addition formula for sinp is known to us” but they did come up with a double-argument theorem for a ...

What is the addition formula for cos? Let a and b be angles given in radians. Then, cos (a + b) = cos (a) x cos (b) - sin (a) x sin (b) What is the sine addition formula? Consider angles a and b whose measures are given in radians. Then, sin (a + b) = sin (a)...
We are going to show that for any angles a, b the trigonometry formula sin (a+b)=sin a cos b + cos a sin b

Solve for sine in terms of complex exponentials (hint: what is the parity of the cosine function?) and the sine formula is suddenly rather obvious.FAQ: Law Of Sines, deducing addition formula What is the Law of Sines? The Law of Sines is a mathematical rule that describes the ...
The trig addition formulas can be useful to simplify a complicated expression, or perhaps find an exact value when you only have a small table of trig values. For example, if you want the sine of 15 degrees, you can use a subtraction formula to compute sin(15) as sin(45-30). ...
