lets take an example to understand it...
Sin30=1/2
If u are given that sin(A+B)=1/2, then what will be A+B? that will be ofcourse 30degree....it means that we can't say sin(A+B)= SinA+SinB
hope u r getting the point as if we write like this then what will be angle A and what will be angle B...thus we can't separate these like that....
hopeit helps....All the best mate
