Question

Is it right to say that sin (A+B)=sin A+ sin B? Justify your answer. b​

Answer 1

No. For example

Sin30+60=sin90=1

But sin 30 +sin60=1/2+root3/2

Answer 2

Answer:

no

Step-by-step explanation:we can answer it by taking examples.

then, now let us take A= 30 degrees, B= 60 degrees

L.H.S= sin (A+B)

=sin (60+30)

=sin 90

=1

R.H.S = sinA+sinB

=sin30+sin60

=1/2+1/$\sqrt{2$

hence its not equal to R..H.S

therefore, sin (A+B)= sinA+ sinB is false
