Question

A=B=45degree
sin(A+B)=sin A cos B +cos A sin B

Answer 1

Hello user

It will be then sin90• = 1

Answer 2

$\sin(45 + 45) \\ = \sin(45) \\ \cos(45) + \cos(45) \sin(45) \\ = (1 \div \sqrt{2} )(1 \div \sqrt{2} ) + \\ (1 \div \sqrt{2} )(1 \div \sqrt{2} ) \\ = 1 + 1 \\ = 2$
I hope it is the answer
