Answer 2

Answer:

Here is ur Answer mate:-

Step-by-step explanation:

State weather the following true or false :-

i)sin(A+B)=sin A + sin B

FALSE

Let A=30° and B=60°

Therefore,LHS =sin(A+B)= sin 30°+ 60°=90°=1 and RHS=sin A + sin B=sin30° + sin 60°

$= \frac{1}{2 } + \frac{ \sqrt{3} }{2} = \frac{1 + { \sqrt{3} } }{2} not \: eqal \: to \: 1$

Hence,sin(A+B)not eqaual tosinA + sin B
