algorithm=\$r = rint(3);
\$f1 = rint(3);
\$f2 = rint(3);
condition: ne(\$r,\$f1);
condition: ne(\$r,\$f2);
condition: ne(\$f1,\$f2);
\$rf = switch(\$r,x^2,cos(x),x);
\$ff1 = switch(\$f1,x^2,cos(x),x);
\$ff2 = switch(\$f2,x^2,cos(x),x);
\$fm = mathml("\$rf");
\$opgaveplot = plotmaple("plot(\$rf,x=-10..10), plotdevice='gif', plotoptions='height=250,
