hi, if i run the below statements, the last 2 cause Maple 12 Student Edition to chug along for a minute then generate a very long answer, like a page worth. it's like it can't figure out the answer and dumps a bunch of garbage. all i am trying to do is a 2nd derivative. restart; dist := t-> sqrt((-27-(60+23*sin(t))*t/sqrt(2))^2+(-11*t+(60+23*sin(t))*t/sqrt(2))^2); 'dist(t)' = dist(t); Ddist := D(dist); 'Ddist(23/60)' = evalf(Ddist(23/60)); tmax := fsolve((D(Ddist))(t), t = 0 .. 1); 'Ddist(tmax)' = evalf(Ddist(tmax)); if i change the 2nd line to the below, then it works fine, and the last two statements print an answer. dist := t-> sqrt((-17-(60+15*cos(t))*t/sqrt(2))^2+(-8*t+(60+15*cos(t))*t/sqrt(2))^2); is this a problem with Maple 12, or am i doing something wrong here ? thanks.
