Solvetrigwarn

-- Option variable: solvetrigwarn Default value: true

When solvetrigwarn is true, solve may print a message saying that it is using inverse trigonometric functions to solve the equation, and thereby losing solutions.

solvetrigwarn:false;
ratprint:false;
errormsg:false;
plot2d(cot(x),[x, 0, 2*%pi], [y, -100, 100]);
limit(cot(x), x, %pi, plus);
limit(cot(x), x, %pi, minus);
is(equal(limit(cot(x), x, %pi, plus), limit(cot(x), x, %pi, minus)));
