RL is correct; your equations are gibberish. You have to learn to use dimensional analysis in your calculations. That is, include the units of the quantities in the calculation as if they were numerical values. This will assure that the calculation is logically correct, that is, the units of the answer will be appropriate to the quantity you derive.
For example, the acceleration of gravity near the earth's surface is 9.8 meters per second per second. What this means is that a falling object will increase its velocity by 9.8 m/s every second.
If an object is dropped from a building and it accelerates at 9.8 meters per second per second for 5 seconds what is its final velocity?
Velocity v (in meters/second) is calculated by multiplying the acceleration a (meters per second squared) by the time t (seconds); as follows:
v = at and substituting values and units
v = (9.8 m/s^2)(5 s)
v = 49 m/s
the seconds unit in the time value cancels out one second unit in the denominator of the acceleration value. The units of the v value are now appropriate for a velocity, because velocity has to have a unit of meters per second. If your v value had come out with units of say, s, then you would know you made a mistake somewhere along the line.
Another example
The distance d traveled by the object under acceleration a over time t is given by the equation
d = 1/2 at^2 or
d = 1/2 (9.8 m/s^2)(5 s)^2
d = 1/2 (9.8 m/s^2)(25 s^2)
d = 122.5 m {The s^2 terms cancel out).
Dimensional analysis helps keep track of your calculation by demonstrating that the units of the result make sense considering the units of the other factors in the calculation. It serves as a check on your work. Until you learn how to do this, your mystic revelations will remain gibberish, they will have no relation to either mathematics or physics, no matter how many websites you quote out of context to try and justify your preconceived opinions.
I'm sorry to be so harsh, but by continuing to make these mistakes you embarrass yourself far more than any one of us can humiliate you. Ignorance alone is no disgrace, but failure to recognize it, and correct it, is.
