Homework Statement
I am told: {\frac {{\it du}}{{\it dx}}}=y and {\frac {{\it du}}{{\it dy}}}=x. Need to find u(x,y) which is a real valued function and prove the result.

Well, I think the answer is of the form u(x,y) = xy + c because...
I am supposed to derive 4\,\arctan \left( 1/5 \right) -\arctan \left( {\frac {1}{239}}
\right) from the complex product of \left( 1+i \right) \left( 5-i \right) ^{4} I do see how the argument of product of the complex expression is equal to pi/4 - 4 arctan(1/5) but I am totally lost. SO how...
Well, Ideally I should be reading 1 value at a time because 4 varisters at once tends to increase the values read inside.
Anyways... Is it possible doing it through a demultiplexer...if I have the input as +5v or something and then use parallel port output bits to set a perticular channel...
well...I have 14 varisters equally distributed on the walls of my room(FCC Structure) which will produce specific resistances depending on the temperature on that place. And my program is to read those resistance values and convert them into temperatures. Then it is to apply larplace's...
Well...thats a lot of current you are talking about! Please fix me up if i am wrong or there is a better way of looking at it! So It would not matter about what current/voltage I input to the charger, as long as I input a fare amount of each over time to make up for the energy I am trying to...
kool...farady's laws...flux and stuff...coil l in mgf B etc...its all coming back...just another question on that...
If I was to store X joules of energy from it to a battery? how would I do it?
Hello
I am supposed to design a hand driven AC generator. I kinda know how to do it. You just have some sort of coil and you rotate it in a magnetic field. Thats all good but for analysis part I am required to give specific information information about no of loops of the coil and total...
