4st(s-t)-6s^(2)(t-t^(2))-3t^(2)(2s^(2)-s)+2st(s-t)

Simplify each of the following expressions: 4s t\ (s-t)-6s^2(t-t^2)-3t^2(2s^2-s)+2s t(s-t)

Simplify (s ^(2) t + t q ^(2)) ^(2) - ( 2 st q) ^(2)

Find the order and degree of the differential equation t^(2)(d^(2)s)/(dt^(2))-st(ds)/(dt)=s

Simplify (t+s^2)(t^2-s)

s-t=3,(s)/(3)+(t)/(2)=6

A particle's trajectory is described by x=((1)/(2)t^(3)-2t^(2))m and y=(t^(2)-2t)m , where t is in s . The speed of the particle at t=4s is:

If displacement of particle is s=(t^(3))/(3)-(t^(2))/(2)-(t)/(2)+6 , then velocity of the particle at t=4 sec. is
