Question

Solve the 9 question in notebook then send ​

Answer 1

Answer:

Maximum A+B

Minimum A-B

Explanation:

You can do it by logic but the method is

As we know

(A+B)^2= A^2+ B^2 +2ABCos a

To maximize A+B we have to maximize Cos a

Maximum value of Cos a would be 1 so

Maximum value would be A+B

Similarly minimum value of Cosa is -1

so minimum resultant possible is

A-B

Hope you understand it..
