Question

Is it right to say that sin(A+B)=sinA+sinB?justify your answer

Answer 1

no it is not correct

Answer 2

No it is not correct
Take an example
Let A=30 and B=60
Now LHS=sin(A+B)
LHS=sin(30+60)
LHS=sin90=1

Now RHS=sinA+sinB
RHS=sin30+sin60
RHS=1/2+root3/2
RHS=1+root3/2
LHS doesn't equal to RHS
Hence sin(A+B) doesn't equal to sinA+sinB
