Yet another question (after scouring the Maple documentation and coming up empty-handed): The following commands: with(student) intercept(y=sin(x), y=0) Result in this output: {y=0, x=0} How can I return the other intercepts with the x-axis? For instance, the first positive and first negative non-zero intercepts? (i.e. the "first" x-intercepts traveling left and right away from the y-axis?) Thanks as always, Bryan

Quick question: in maple , sqrt(4) returns 2. Why not plus/minus 2, since -2 is also a valid square root of 4? Thanks! Bryan
