Dear tejas akole



let x+2 =t2

dx =2 tdt



=2t-2∫(1+1/t2)dt/{(t-1/t)2 +3}

now put (t-1/t) =u


=2t-2∫du/(u2+3)   +c

now solve and put tha value ou u and t in terms of x

If sin(A-B) = ½, cos(A+B)= ½, 0 B, find A and B.
Assume A-B = alpha and A+B = beta. Now, Since sin (alpha) = cos (beta) = ½. Therefore alpha = beta = pi/4 Now solve the two equations A-B = pi/4 and A+B = pi/4. and find A and B....
