    Kirchhoff's Laws and current through resistors

    Question: The diagram below shows a circuit where; R1 = 5.00 Ω, R2 = 6.00 Ω, R3 = 1.00 Ω, V1 = 4.500 V, V2 = 20.00 V, and V3 = 6.00 V. (In solving the problems that follow, initially pick the current directions as shown. If the actual current turns out to be in the opposite direction, then...

    Intermediate Value Thoerum?

    Homework Statement Show that the equation e^x = x + 2 had exactly two solutions. Explain your reasoning. Homework Equations Okay so I guess I'm using the intermediate value theorum and proving that f(a)f(b) < 0 we can find a c and d such that f(c) = 0 and f(d) = 0 so that by...
