If sin(A + B) = 1 and cos (A - B) = 1,0° < A+B S 90°, find AIf sin (A + B)B find A and B. |

Answer» Answer: A=1,B=0 taking A+B=1 and A-B=1( because if we take 0 then value of a will be halved and B will be 1) elimination method A+B=1 A-B=1 and when this is transferred to eqn1. 1+B=1 value of B will be 0 as FARED. |
