I have this function:

And I was trying to solve for z with the help of an iteration.

I start at

z(0) = 0.748

z(1) = 4.359

z(2) = -0.224

But for example, if I use almost the same function

I can find the solution

Hence my question is what value or method I should use to be able to solve it?]]>

I am not very new to electronics but new here.

I have been doing electronics in the past but in a very practical way, not dealing with any kind of theory and calculation. Lately, I have been studying some mathematics, physics, and some theory of electronics and so I'm calculating some things.

I am familiar with how to round numbers off for example when you're solving a physics or chemistry problem, rounding numbers off, significant digits and the whole story but it seems...

I want to indicate its capacity on LabVIEW. So I just need some multiplier and scaling factors for the voltage. Although, I don't know how exactly.

Equation: 5.4857x - 7.1607

The bin is 25" high. So 25” – z (inches) equals the capacity. For instance:

1 mV → 8” = 5340.7 in^3

3 mV →...

Code (C):

- public class Vector
- {
- public double X;
- public double Y;
- public double Cross(Vector v)
- {
- return X * v.Y - Y * v.X;
- }
- }

It returns a scalar quantity.

Can someone please tell what this is called and what the result represents, please?]]>

Here is a special challenge with a relatively simple circuit. It's a voltage divider of sorts, but performs an attenuation of the AC input signal.

This is special not only because of the current dependent resistor, but because it challenges the basic theory of how we usually evaluate a transistor circuit when we include the internal resistor value we usually refer to as 're'.

Because of that analogy to a similar transistor circuit, i ask that you analyze this circuit two...

News reports frequently suck because they tell you so little about what happened and, instead, stoke your emotion. This is certainly no exception and now a high-powered lawyer has taken it on. Basically (

(A,B is an events.)

my question if A doesn't occur, that means there's a possibility that A satisfy that "specific statement", also there's a possibility A will not satisfy that "specific statement", so we don't have definitely data what's going if A doesn't occur, so we can't claim that if A doesn't occur, then definitely the specific statement satisfied !]]>

lets assume I have four continues blocks which every block is size of k, so if I need the total size it's 4k and it's easy !

but what's confusing me, between one block and another there's a bound and it's also taking a size of, so the total size of all the blocks isn't exactly 4k and that what's...

Here is a little challenge. The idea is to simply calculate the input impedance looking into Z1.

This is with all the impedances (Z1, Z2, etc.) made into a pure resistance with value equal to the subscript.

So Z1=1 Ohm, Z2=2 Ohms, Z3=3 Ohms, Z4=4 Ohms, Z5=5 Ohms.

Hint:

Zin (which is actually Rin with all resistors) is either equal to 8/15 Ohms or 15/8 Ohms. Or am i wrong?

Warning: This might be more difficult than it looks like at first glance.]]>

then it's equal to say that the condition itself fulfills in other words i<sqrt(n), but why? why it's the same to say that thing if I have changed the prime condition?

may anyone please explain me the logic of equinumerosity in math?]]>

So how do I calculate the distance? I have probably done it a million years ago but it is slipping my mind now,
