The k's in the two displayed equations at the top should be upper case.

The diffusivity value for myosin should be 0.11, therefore the time to cross 0.01 mm is 5 seconds and to cross 1 mm is 50,000 seconds.

The capacitance of the axon membrane is about 1 microfarad; this is 1 times 10 to the MINUS 6th power farad.

The file exer964.m in Problem 5 should be Yprime=[-k1*Y(1)+km1*Y(2); k1*Y(1)-(km1+k2)*Y(2); k2*Y(2)]; (km1 in place of k1).

In the displayed equation for minus A inverse f the first component of f should be 493/10.

The Jacobian was computed with a different set of parameters, namely h=1.1, rho=0.024, R=0.86, tau=0.38. When computed with the values in Table 11.4.1 the Jacobian is

[-0.04 0.222 0.032 -0.045]

[-0.23 -0.107 -2.129 -0.478]

[ 0.28 -0.114 2.097 0.523]

Maple code to compute the Jacobian is

restart;with(linalg):

beta:=h/(exp(h*tau)-1);

RHSmatrix:=matrix([

[-h,rho,beta],

[h,-rho-r,0],

[0,r,-beta],

[1,1,1]

]);

Z:=vector([0,0,0,1]);

eSol:=linsolve(RHSmatrix,Z,'rnk',v);

jc:=jacobian(eSol,[h,rho,r,tau]);

evalf(subs([h=1.99,rho=.074,r=.113,tau=1.5],evalm(jc)));

At the top of the page, the coefficient c sub 5 should be c sub 6.
