If the anterior tibialis is the agonist during dorsiflexion, which muscle group acts as the antagonist?

For the following reaction; 2A + 3B –> C A is a second order reactant, and B is a first order reactant. The general rate law is:  rate = k[A]a[B]b … You can use the desmos online calculator. a) If [A] is 0.65M and [B] is 0.008M when the rate of the reaction is 1.4 x 10-2 M/s, solve for the rate constant for that reaction.   b) using that rate constant, solve for the rate of the reaction when [A] is 1.4 x 10-4M and [B] is 2.75 x 10-2M   c) for the same reaction, solve for [B] if the rate is 1.4 x 10-3 M/s when [A] is 0.7M

Consider the following approximations for the first derivative: (forward difference formula}) (center difference formula) In class, we learned how the truncation and round-off errors for the center difference formula are proportional to h2 and , respectively [assume machine precision is ]. Minimizing the total error, yields an optimal step size . (a) The truncation and round-off errors for the forward difference formula are proportional to h and , respectively. Minimize the total error to find the optimal step size . Hint: < . [10 points] (b) Evaluate the derivative of at x = 1 using the two formulae with their respective optimal step sizes.
