    Help with Node Voltage Analysis

    Say you are analyzing a circuit. Will the node voltages depend on where you set your reference node? Because, i did a circuit problem and set the reference node to a different node each time and, i got the same answer overall, but my potential across a certain node was different each time. Am...

    Proofing: sqrt(7+sqrt(48))+(sqrt(7-sqrt(48))=4

    ok, thanks dude...i got as far as your third step before i realized that you posted again...i realized my error... thanks for the great help guys!

    PHYSICS PROBLEM-should be easy for AP students

    yea man, just set it up like a right triangle with vertical velocity and horicontal, with the actual velocity as the hypotenus...it should be easy to solve then

    Proofing: sqrt(7+sqrt(48))+(sqrt(7-sqrt(48))=4

    that would change the value...i would have to also square the 4 on the right side...which is against the rules of the problem

    Proofing: sqrt(7+sqrt(48))+(sqrt(7-sqrt(48))=4

    wait a sec, what is the lhc...to not change the value, wouldn't i have to multiply it over itself if i wanted to get teh a^2 -B^2? can you clarify what you mean?

    Proofing: sqrt(7+sqrt(48))+(sqrt(7-sqrt(48))=4

    yea, i did that already, but the problem is, then i have complex radical denomintaors...

    Proofing: sqrt(7+sqrt(48))+(sqrt(7-sqrt(48))=4

    i need help proving that (sqrt(7+sqrt(48)))+(sqrt(7-sqrt(48))) = 4 the limitations are that you cannot manipulate the right side...only the left.. so basically, i need help simplifying the left down to be 4 thanks..
