Hi everyone, I am a third-year electrical & computer engineering student trying to find out what career is best suited to my interests. In the first two years of my degree, the courses I enjoyed the most were programming, linear algebra, calculus, differential equations, complex calculus, and...

\Phi = B_avg * A for this situation, I believe. The test coil isn't moved once it is inside the field coil, so the effective area doesn't change.

Anyone? :(

Homework Statement (This is a bonus question for a lab I have coming up next week.) In this part of the lab, a large field coil is hooked up to a function generator that outputs a 100 kHz, 10V peak-to-peak waveform. A smaller test coil is connected to an oscilloscope and slowly inserted into...

Hey everyone, I am a first year student in electrical/computer engineering at the University of Toronto. I have experience working in Java and C, and my major projects are an Android app and an employee database program built in Java (Netbeans, Java Swing API). I would like to request some...

Homework Statement Find the value of the limit as x goes to 0 of ((sin(x)/x) - 1) /x WITHOUT L'HOPITAL'S RULE.Homework Equations The Attempt at a Solution I tried to get the expression inside the limit in terms of the fundamental trig limits, but all I got to was (1/x)*((sin(x)/x) -1). I want...

I believe that's the Dirichlet function, and I don't think that limit exists...:S

Hey everyone, When I first started learning calculus, I was taught that the first thing to do when asked to evaluate a limit as x -> a of f(x) is to evaluate f(a). If f(a) is of the form 0/0, then no conclusion can be made about the limit, and the expression needs to be manipulated by...

Hey everyone, I'm writing a simple program to calculate the monthly payment amount for a loan given a principal, down payment, finance term, and interest rate. The monthly payment needs to be reported to the user rounded to two decimal places after they have entered all the required...

Oh. Now I feel dumb :(. Can this "problem" be solved with single-variable integration, though?

Homework Statement Having recently learned the disk/shell/washer method for finding the volume of a solid of revolution, I'm trying to apply similar methods to derive the formula for the surface area of a cone (and hopefully after that, that of a sphere). The region that is revolved around...

Homework Statement "An electron is fired from a negative plate towards a hole in a positive plate. It then passes between two parallel plates that are 3 cm long and 2 cm apart with a voltage of 550 volts across them. If the accelerating voltage across the two original plates is 900 volts what...

I accidentally used q = 4e for the alpha particle (since m = 4 x mass of proton)... ^.^''' Thanks, guys!

Homework Statement "If an alpha particle is fired straight at the nucleus of an uranium atom (q = 92e), at a velocity of 5 x 10^5 m/s, how close will it get to the uranium nucleus? Homework Equations Ek = (mv^2)/2 Ee = (kq1q2)/d The Attempt at a Solution Since the alpha particle and...

Homework Statement A 4.5 kg metal sphere is released in a fluid where k = 10.5 N s^2/m^s. How long does it take to reach 90% of its terminal velocity? Homework Equations Force of drag = kv^2, where k is the drag coefficient (I believe we're not considering buoyancy.) The Attempt at a Solution...
