2. Einstein Summation Convention Einstein Summation Convention: When an expression contains one index as a super script, and the same index as a subscript, a summation is implied over all values that index can take Examples: where the expression still represents four equations. An index that is summed over is called a dummy index, and can be replaced by another index if convenient. e.g The index in the above expression is not involved in the sum operation. Such an index...

Given a 3-compartment first-order kinetic model, and ending with 1015 atoms of the 2nd progeny (3rd compartment) after 100 hours, use Bateman equations to predict the number of atoms in the 1st compartment at time zero. The half-life of transfer from the 1st to 2nd compartment is 15 hours, the half-life of transfer from the 2nd to 3rd compartment is 30 hours, and the half-life of transfer out of the 3rd compartment is 25 hours.Given a 3-compartment first-order kinetic model,...

Α'2 = Σ Λ Α' (4.4) V=1...2 The instructions under the summation symbol tell us to assign the values t, x, y, z to the index v and sum the four terms that result. The value of u is left unspecified: if = 1, then this equation corresponds to the first row of equation 4.1; if u = x, it corresponds to the second line of 4.1, and so on. Equations 4.4 and 4.1 are equivalent. Equation 4.4 can be...

Problem 5. Consider the following second order linear differential equation f"(t)-f'(t) +f(t) kt which models a forced oscillation in a damping material. For example, imagine moving your hand back and forth underwater. Write this equation as a set of coupled first order equations by doing the following: ·Define a new function g = f'(t). This gives you one of the two coupled equations. . Use the given ODE, g, and its derivatives to write the second first order equation. Both...
