I'm new to Maple, and I was hoping someone could help me! I have a formula for a hyperbola, 9x^2-y^2-72x+8y+119=0, and it states to find the standard form. The standard form is supposed to be two fractions that are set equal to 1. I have Maple 10, and the only thing I've been able to find so far has been to select "apply a command" from the context menu and type in "completesquare", but either I'm missing a step, or I'm doing something incorrectly. Any help would be greatly appreciated!! Thanks!

I'm trying to enter a piecewise function with three parts, but can't seem to figure out how to make an extra line (the "expression" selections have one, but it only allows two lines to be entered). I read somewhere else to do CTRL+Shift+R, but that didn't seem to work. What I'm trying to enter is
y=x^2-5 x<2
-3x-7 -x<-2 and x<5
abs value(x-2) 5<x

I can get the first two lines, but can't find a way to include the third line. I'm supposed to graph the function so that all 3 are shown (may not be connected), and then I have to evaluate f(-3),f(3), and f(7). I haven't tried the evaluate part, because I can't seem to get all three components to graph. I have Maple 10. I'm new to Maple, any help would be greatly appreciated, this is quite the learning experience!

I have a problem that I'm somewhat confused about and I'm looking for help if possible. The problem states: Given the equation (x^2-1)/(x-1)=0, graph on an appropriate scale. What is the domain, what is the solution, and what are the x and y intercepts? I'm not sure how to put this one into Maple, if anyone can help I'd greatly appreciate it! This is my first time using Maple and I'm a little confused. I have Maple 10. Thank you! Stacey

Help please! I have a problem that states "use implicit plot to graph 3x^2 + 2xy + y^2 = 4 on the interval [-5,5]". I'm not sure how to do an implicit graph, or how to identify the interval to plot. If anyone can help me, please let me know, I've been working on this one for hours (I have Maple 10). Thank you, Stacey

I'm hoping someone can help me. I'm trying to find the equation of a circle using three points (2 outside points and the midpoint). I tried typing this from the Maple software help menu, but keep getting an error: > with(geometry); _EnvHorizontalName := m; _EnvVerticalName := n; > circle(c1, [point(A, 0, 0), point(B, 2, 0), point(C, 1, 2)], > 'centername' = O1); > center(c1), coordinates(center(c1)); Error, (in geometry:-circle) the coordinate names must be a list of two names Error, (in isassign) the first argument is expected of type name > My three points are actually (-4,-9), (6.7), and the center is (1,-1). I've worked on this for days, but can't seem to get anywhere. If anyone could help I'd greatly appreciate it!
