OK, I checked my derivation again, this time using a much more appropriate notation. In Mathematica, I've written down this expression (please check the truth table): (a1 || a0 || b1 || (! b0)) && (a1 || a0 || (! b1) || b0) && (a1 || a0 || (! b1) || (! b0)) && (a1 || (! a0) || (! b1) || b0) &&...

First, I shall reply to @phinds. A task we were given states that inputs A and B consist of two bits, namely A1, A0 and B1, B0. I should also note I have no experience building circuits, so it is possible my comprehension of the problem is completely fallacious. @berkeman, thank you for...

At our class on digital structures, this assignment has been given. It's a preparation for upcoming lab work, and I'm not sure my design is correct. Is anyone please willing to check it out? 1. The problem statement, all variables, and given/known data Design a two-bit comparator using NOR gates...

Now that's actually helpful. So if ##y=x## represents such plane, then the curve I'm looking for must be a circle! Is my assumption correct? Because if it's circle I'm after, then I could use ##x = \cos{t}##, ##y=\sin{t}## and ##z=\cos{t} + \sin{t}## for ##t \in [0,2\pi]##. Please correct me if...

Hi everyone! I'm a student of electrical engineering. At my math class, we were given a problem to solve at home. Now, from what I've managed to gather, this is a trick question, but I would like to get someone else's opinion on the task. It's also worth mentioning that parametrization is a...

OK, first of all, I would like to thank everyone for helping me on this question. I honestly couldn't wish for a better support, I truly appreciate your time and effort. thank you! ------------ I now understand that for task 1 (second part of it) I need to solve a system of equations that...

Presumably, you mean the first task. Parallelity means that they lie along the same line passing through the origin, or that their cross product is zero. Parallel vectors are scalar multiples of one another. Also, vectors in the first case are linearly independent (determinant of matrix ## A##...

Hello, everybody! I would really appreciate if someone could help me understand how to solve the following two tasks. I am not sure whether my translation is correct, so if, by any chance, you know a more appropriate terminology, please let me know. I am not fluent in writing matrices here on...

Thank you so much, to the both of you! I cannot express my gratitude enough! It's been bugging me for a long time... and now as I see how easy it actually is. Thanks again!

Homework Statement I came across a pretty interesting question that asks for magnetic flux density (B-field) on the axis of the equilateral triangle. This axis is meant to be perpendicular to triangle's surface passing through its centroid. Assuming that a triangle has sides denoted ##a## and...

Hello! Recently I was going through some old exams and upon encountering this problem (which seemed pretty easy) I got stuck. Exams at my university are composed of individual tasks, each having three subquestions with four plausible answers respectively. Solution sheet gives results only, so...

Interesting to know that, because I know my translation is correct. It explicitly asks to compute force on cardboard sheets, so apparently it's a trick question. Thank you so much for helping me! Both you and @rude man, thank you!

To begin with, I would like to thank both for participating. Third question, as explained above, has four plausible answers. Solution sheet gives ##F=945N##, but you can chose from ##F = 307 000N## ##F=0.0038N## ##F=0.0019N## So if you deem that force of 945 Newtons is inaccurate, could it be...

Thank you so much! I was wondering how andwhy, but now I finally understand it. Thank you so much for helping me on that one ;)
