    Solving for x in 0 = -1/8 + 3/8 x / (10^2 +x^2)^0.5

    That bit of differentiation was given in their hints: And yes, 6.04s will do me just fine. :)

    Solving for x in 0 = -1/8 + 3/8 x / (10^2 +x^2)^0.5

    Aha! I was making a foolish error at the final step. It can be rearranged and input into the quadratic formula to get the same answer. Carefully writing out this post helped me to get there, so I'll leave this here for anyone that wants to discuss it.

    Solving for x in 0 = -1/8 + 3/8 x / (10^2 +x^2)^0.5

    Hello all, I've solved this problem on IP by writing the relevant equations into Gsheets and solving through trial and error. I've followed their hints for solving it, which lead me to a rather complex quadratic to solve. I'd appreciate if anyone can give me a clue as to how to solve for x in...

    B What Is the Physical Significance of Logarithmic IV Graphs in Diodes?

    Hello there, I've been working through a task (that doesn't have an answer sheet or explanation) in which we plot I against V for three different diodes. Each has a different threshold voltage and displays the usual charcteristic curve. The final question is this: "It is suggested that the...
