An airplane is flying at a height of 1960m in the horizontal direction with a velocity of
360 km/hr It drops a bomb. The bomb strikes a point on the ground, then what's the time t took by the bomb to reach the
ground ?
1=0.9999... true or false ? Who can proof it ?
Let x = 0.999.. (eq1)
If you multiply both sides by 10
You will get 10x= 9.99.. (eq2)
Lets subtract eq1 on eq2
Eq2 - Eq1
10x=9.99
X=0.999
9x=9.00
Which means x=1 i.e x=0.999
Don't I have proved it ?
Anyone dare ?
