Please, I need help ASAP solving this.

In the 1950's. Dr. L.A. Woodbury of the University of Utah School of Medicine developed electrical models for the study of convulsions. One such model is shown in the figure below. C1 represents the volume of drug-containing fluid. R1 is the resistance to the passage of the drug from the pool to the blood stream, C2 represents the volume of the blood stream and R2 is equivalent to the body's excretion mechanism (kidney, etc.). The concentration of the drug dose is represented as V0 and the voltage nu a(t) is analogous to the amount of drug in the blood stream. Determine the s-domain equation for Va(s) and put the equation in the standard form for factoring. Determine the concentration of drug in the blood stream as a function of time. i.e. find nu a(t) if C1 = 1 mu F. C2 = 8 mu F, R1 = 9 M Ohm, R2 = 5 M Ohm and Vo = 100 V. [10]

Explanation / Answer

1. If z = f(x, y) = x4y3 + 8x2y + y4 + 5x, then the partial derivatives are. ?z. ?x ... 2. If z = f(x, y)=(x2 + y3)10 + ln(x), then the partial derivatives are. ?z ... y x+y+z. , then the partial derivatives are. ?w. ?x. =(x + y + z)(0) ? (1)(y). (x + y + z)2. = ... 1 x d dx. (sin(x)) = cos(x) d dx(cos(x)) = ?sin(x) d dx ( sin?1(x)) = 1. ?1. ? x. 2 d dx ...
