A particle falls from the top of a tower and it cover `(3)/(25)` of the total height from `t=2` sec to t=4 sec. The height of the tower is:-
`h_(1)=5(2)^(2)=20` `h_(2)=5(4)=80` `h_(2)-h_(1)=60=(3)/(25)H` H=500m

`d/(dx)sqrt((1-sin2x)/(1+sin2x))i se q u a lto,(0<x<pi/2),` `sec^2x` (b) `-sec^2(pi/4-x)` `sec^2(pi/4+x)` (d) `sec^2(pi/4-x)`
`y=sqrt((1-sin 2x)/(1+ sin 2x))=(cos x - sin x)/(cos x + sin x)=(1-tan x)/(1+ tan x)=tan ((pi)/(4)-x)` `therefore (dy)/(dx)=-sec^(2)((pi)/(4)-x)`
