v1

(9v + 1) + (3v + 1)

(V + 1) / (V (2V + 1)) dv = - (1) / (x) dx

(1+tan^(2)v)(1-sin v)(1+sin v)=1

In H- atom spectrum V is the wave number V_(1)=V_(min)+V_(max) for layman series V_(1)=V_(min)+V_(max) for balmer series then V_(1):V_(2)

If |vec(V)_(1)+vec(V)_(2)|=|vec(V)_(1)-vec(V)_(2)|and V_(2) is finite, then

If vec(v)_(1)+vec(v)_(2) is perpendicular to vec(v)_(1)-vec(v)_(2) , then

A car moves with speed v_(1) upto (t)/(3) time and then with speed v_(2) upto next (2t)/(3) time. Path is straight line.What is the average speed of car? " (A) (2v_(1)v_(2))/(v_(1)+v_(2)) (B) (v_(1)+v_(2))/(2) (C) (2v_(1)+v_(2))/(3) (D) (v_(1)+2v_(2))/(3)

If |u|<=1|v|<=1 and z=(u-v)/(1-ubar(v)) then least value of |z| is
