Rearrange Equations: Making J the Subject - Need Help

AI Thread Summary

To isolate J in the equation V = (J/2 + 4a/3) / L, first multiply both sides by L to eliminate the denominator. Next, subtract 4a/3 from both sides to simplify the equation. Finally, multiply the resulting equation by 2 to solve for J. Following these steps will yield J as the subject of the equation. This method ensures a clear path to rearranging the equation correctly.

SO here is the problem

I am wondering how to make J the subject ?

I have tried making J/2 and 4a/3 into a single fraction but so far nothing.I am doing something wrong somewhere.

Any suggestions ?

Here it is so I can see it better:
V = \frac{\frac{J}{2} + \frac{4a}{3}}{L}

Multiply both sides by L.
Subtract 4a/3 from both sides.
Multiply both sides by 2.

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
