t=2pi sqrt((r^3)/(gm))
Divide both sides by 2Pi
T/2Pi = sqrt(r^3/gm)
Square both sides:
(T/2Pi)^2 = r^3/gm
Multiply both sides by m:
m*(T/2Pi)^2 = r^3/g
Divide both sides by (T/2Pi)^2:
m = (r^3/g)(2Pi/T)^2
Next question: a/b + c= a/d
a/b=a/d -c
a = (a/d-c)b
a/(a/d - c) = b
Last question: d = vt + (1/2)at^2
d = vt + (1/2)at^2
d - (1/2)at^2 = vt
Divide both sides by t:
d/t - (1/2)at = v

Swap sides:
Multiply both sides by 
:
Square both sides:
Multiply both sides by 
:
Take the reciprocal of both sides:
Use similar techniques to solve the other two problems.
