Question

Find the answer. sin(A+B) + cos(A+B)
​

Answer 1

Recall the compound angle formulae:
sin(A+B) = sinAcosB + cosAsinB
cos(A+B) = cosAcosB - sinAsinB

sin(A+B) + cos(A+B) = sinAcosB + cosAsinB + cosAcosB - sinAsinB

I think?? It looks a little too complicated to be the answer though

(Btw this is Math haha why is this question under English)
