Accurate formula for calculating filter capacitor size on a linear regulator.

$C = \frac{I}{V_R} \times \left(\frac{1}{4f} + \frac{arcsin{\left(\frac{V_{IN}-V_R}{V_{IN}} \right)}}{2\pi f} \right)\\ C=\text{Minimum capacitance required}\\ V_R= \text{Maximum ripple}\\ V_{IN}= \text{Input voltage, excluding diode losses}\\ I=\text{Current drawn by regulator}\\ f= \text{Frequency}\\$

Factorise:
2 a squared x b squared = A etc?
+ 2 b square c square = B
+ 2 a square c square = C
- a raised to the power of 4 = D
- b raised to the power of 4 = E
- c raised to the power of 4) = F
/ 16.
The whole expression is under root.
In American English, do you mean
X = [(A+B+C-D-E-F)/16]^0.5, so if A = 6, B= 5, C = 4 and so on, then X = 0.75?

and B, for example, = 2(b^2)(c^2), so if b = 2 and c = 3, then B = 72?

so I should come up with a general equation that solves for a, b and c?

If that's what you mean, I'll give it a try, but if I can't solve it in 10 pages I will quit.

Whay are you responding to a post made over a year ago?

Aslo this thread is about the Latex feature of this forum, not maths help.

why when I type a latex command into Word, it doesn't convert it?

in otherwords, in what softwares can Latex be used?

It probably would have been better to start a new thread, considering this one is 6 years old!

Word has its own equation editor that works differently from the latex editor here on the site. Depending on your version, you'll probably have to go to "Insert" and select "Equation". It doesn't take commands, though. The software is completely different, which is why it doesn't convert it automatically for you.

To my knowledge there is no Latex in Word. Only the equation editor.

Sorry Tony but I am not going to ask WTF, this time...
