1. ### What’s 470 pF in farads using engineering notation? How?

'Pico' means 10^-12. So 470 pF is 0.000000000470 farads, or 470 * 10^12 farads.

2. ### If the height of an equilateral triangle is also a root pf the equation y^4-3y^2-270, then the area of the triangle is?

y^4 - 3y^2 - 270 = 0 y^2 = (3 +/- sqrt(9 + 1080)) / 2 y^2 = (3 +/- sqrt(1089)) / 2 y^2 = (3 +/- 33) / 2 y^2 > 0 y^2 = (3 + 33) / 2 y^2 = 36/2 y^2 = 18 y = +/- 3 * sqrt(2) y = 3 * sqrt(2) So, the height is equal to 3 * sqrt(2) (s/2)^2 + h^2 = s^2 (s/2)^2 + 18 = s^2 s^2 / 4 + 18 = s^2 18 = (3/4) * s^2 18 * (4/3) = s^2 24 = s^2 2 * sqrt(6) = s A...

6. ### how to do calculus question?

Let's compute the total derivative (or Jacobian or whatever you want to call it) of f, Df at an arbitrary point. To be explicit: we have F(x,y,z) = (f(x,y,z), g(x,y,z), f(x,y,z) + g(x,y,z)) for all (x,y,z) in R^3. Letting h_j denote the partial derivative of a function h with respect to...

8. ### Even degree and odd depree polynomial functions?

Hint: show that k(-x) = h(x). Then it follows that k is the reflection of h in the y-axis. If we were looking at odd degree polynomial functions with the same structure, you would find that k(-x) = -h(x), and that k is the reflection of h in the origin (or h...
