Question

? For what value of A and B given below sin (A + B) = sin(A)+ sin(B)?​

Answer 1

Answer:

A=0,B=90 or A=90,B=0

Step-by-step explanation:

sin90=1,sin0=0. sin (A + B) = sin(A)+ sin(B). sin(0+90)=sin0+sin90. (OR) sin(90+0)=sin90+sin0. sin90=sin90+sin0. 1=1+0. LHS=RHS. SO the values of A and B are 0,90 even if we put the values of A and B as 90,0 we get the same answer. HOPE THIS HELPS YOU
