Thanks Bill! It works nicely. I'm self-taught so I ignored Show[]'s existence. Now I know. That's an interesting hack, although I guess for most purposes computer-generated numbers work fine ... and are simpler to obtain. Thanks again

Hi all. Is there a way to plot both functions and coordinates/points on the same graph in Mathematica? The various functions for plotting each seem very incompatible. I would like to compare a probability function to Monte-Carlo-method simulation results. Also, out of curiosity, do...

You're right, i did the math again through mathematica and i got a slightly different equation: -\frac{2436.77 Sin[377 t]}{x^{0.8285} Cos[377 t]^{0.1715}} = 170 x Cos[377 t] + \frac{5.24172 Cos[377 t]^{3.314}}{ x^{3.314}} - \frac{232.031 Cos[377 t]^{4.1425}}{ x^{4.1425}} This is not the result...

Hello everyone, I have an implicit equation: -155.034 x^4 ×sin(377 t) = 0.0524166 x^6 × cos^{1.414}(-377t)-(0.0581964+0.0442696 i) x ×cos^4(377 t)+7.09332 cos^5(377 t) I would like to create a plot of this function using Mathematica, but I am not very proficient with this software, and...

I asked an ECE phd student I recently met about this, and he told me that it would only impede the current from reaching an infinite amount if it were alternating. Probably though, for direct current, capacitance (I guess normal wires have tiny capacitance just as inductance?) would kick in...

I know those things are not possible, I was just speculating. There's no need to get heated. Anyways thanks for replying. I took a little time to look more extensively and i found the following: But maybe you're right. What particular mechanism did you have in mind?

I was wondering, since resistance decreases along with temperature for most metallic conductors (usually power function), in theory, if this conductor were to be at zero kelvin, would the resistance of this material also be precisely zero, or would it just be some extremely small value? If it...

I talked to my physics teacher, he thought the insufficient current explanation was valid for the problem I was having. I'll try with a 9V battery and a flashlight bulb. The temperature will be similar, but the different resistance and voltage will allow the smaller amount of current to go...

Thank you for replying. Truesearch: I was using a Vernier probe to graph the current and the frequency of measurements I think was 20 per second. I did try higher frequencies but then the graph was pixelated and fuzzy and with too much noise. Is 0.05s precise enough in your opinion...

Hello everyone, I have been working on my extended essay (IB) in physics these past few months, and my topic is the current surge that occurs when a light bulb is first turned on, due to temperature. I have finished all the math/theoretical part for this, and long story short, as I expected...
