To calculate standard time, subtract the equation of time from the sundial time, then subtract the longitude from the answer you get.
V=distance divided by time
Speed= distance over time. :)
velocity=acceleration multiplied by time
Speed= distance over time. :)
By calculating the discriminant of the equation and if it's negative the equation will have no solutions
There are a great many equations for calculating current; it depends on the context in which you need to calculate current.

density = mass/volume
a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.

wave speed= frequency/wavelenth
Frequency F = h/energy = c/wavelength
