The documentation for solving equations says that SOLVERADCAN allows
more equations with exponentials and logarithms to be solved.
SOLVERADCAN:TRUE;
SOLVE(log(a*x)=C*log(b*x),x);
does the trick.

Reading the section on Trigonometric functions says to use TRIGSIMP
for simplifying trigonometric expressions.
TRIGSIMP(a*sin(x)^2+a*cos(x)^2);
will work.

>From reading the description of SOLVE I decided to give it a helping
hand by dividing by EXP(b*x),
q:EXP(a*x)=C*EXP(b*x);
SOLVE(q/EXP(b*x),x);
which works ok. Probably a guru can point out a better way. I only
started learning about the SOLVE command this morning.
