3107*. For a rectil<strong>in</strong>ear homogeneous rod whose axis co<strong>in</strong>cides<br />

with the Jt-axis, the temperature u = u(x, t) <strong>in</strong> a cross-section with<br />

abscissa x at time /, <strong>in</strong> the absence of sources of heat, satisfies<br />

the equation of heat conduction<br />

di<br />

where a is a constant. Determ<strong>in</strong>e the temperature distribution<br />

for any time t <strong>in</strong> a rod of length 100 cm if we know the <strong>in</strong>itial<br />

temperature distribution<br />

u(x, 0) = 0.01 A; (100 x).
