Theoretically only, would a capacitor of infinite capacitance be considered an open circuit?
What would it be used for in application if it did exist?
The reason I am asking is because I have a homework problem where it is used with a JFET transistor in a circuit.
If I can't solve the...

just a small part of a large problem ><a I am not even sure if this is in the right place. the first two questions i have to ask are really minor so i didnt want to make separate threads for each one. the third one is an actual problem itself tho.
(1) i need the laplace...
i would do integration by parts on the 1/x and the tan(x) then work from there.
probably let tan(x) equal sin(x)/cos(x) and use substitution integration to solve that part
then when you've solved the integration, sub in infinity and just logic it out from there i guess.
sorry if its...
Homework Statement
someone asked the ellipsiod problem before and i didnt under stand anythign in the repsonces >< but i had already gotten this far that my equation (simplified) is
cos(theta)*sqrt[cos^2(theta) - (x^2)/(a^2)]
i need to integrate this equation with respect to d(theta)...

(sorry about the random apostrophe's in some of the writing, i don't want someone to just google and take my working ><. i don't know if the apostrophe thing works though...)
i have two different methods but i don't think either is right...
I'm still not making any progress on that problem. =\
@carbz: I've learned trig already, I'm studying in Uni right now (but like you said, there's not enough info to use trig). The frustrating part is that the problem comes out of a grade 10 book and I'm having so much trouble with it. I...
19 minutes ^^;
Wrote down the clues twice each to remember them (the second time around I slightly categorized them to make them easier to find), then drew a table of 5x5 and filled it out. >< I didnt even realize when I finished that one of the slots was still missing a pet till I read here...
Thanks for the responces ^^ I'm glad to know I'm not the only one who thinks the question is really strange. =]
I took another look at the original question and it's the same. The angle b forms on the radius within the circle and not on the circumference, the drawing was given in the...

its a four part question but the first part has me stuck:
the question:
A particle of mass m is accelerated from rest by a constant force F along a straight line for a duration of time t. Use relativistic mechanics unless explicitly stated otherwise. Also remember that the definitions of...
@jpr0: thanks for checking
yeah, i figured there would have been a much easier way to get this done but i couldn't find one. how else could it be done?
was that last line supposed to be 26 and 24 instead of the 25 and 23 (respectively)
in that case should i have stopped at

this is the problem and I've worked for mostof it, but I am not sure I've got the right way to go about it, or if the ansewr i have found it right.
