I want to plot ,
utheta= -k*ln(ro/r)
where k=10 and ro=1000
for angle theta = pi/2 and theta = 3*pi/2 only where theta is measured from negative y axis.
How do I plot this. I am not getting , please help me.

t = linspace(pi/2,3*pi/2) ;
k = 10 ; r0 = 1000 ;
r = r0*exp(t/k) ; % on solving the give equation for r
plot(t,r)

no range for theta. utheta is a function of r only.

no utheta is a dispalcement in theta direction which is a function of r only.
