MaplePrimes Questions

I've got a promblem now. My teacher wants me to write a normalized programme with maple, yet I do not know how. I would like to know where can I find a normalized programme with standard format. If anyone who are familar with this subject, I am glad to accept your suggestions. Thanks very much:)
I could use a hand with a problem our class has. we have the function xy+yz+zx=3 I would like to find a way to graph the surface, the tangent plane at the point (1,1,1) and the normal line all on the same graph. We have tried a couple different methods and have failed miserably. We are using Maple 10 Thanks in advance! Michael
Hi How do I plot and solve Gabriel's Horn in maple. I will really appreciate your help. Take care
How do I integrate a purely numerical function, say f = evalhf @ sin,
and using the NAG routines only ?
In linear algebra multiplication of a scalar and a matrix can change order: aM=Ma, where a is a scalar and M is a r by c matrix. In case of four matrices K,L,M,N the product KLMN is the same as LMNK if the product LMN is a scalar. However, Maple does not allow the forementioned change of order, because the program only checks whether adjacent matrices are conformable. How can this change of order be done in Maple? The issue is that I want to check my work using Maple. TIA Harry ps. is there a brief notation in Maple for scalar by matrix multiplication?
I would like to know how do I find the area under a curve. The curve is 2 D and the data to plot the curve is available. Thanks you

hello! i have a problem that drives me crazy the last days. i'm a switcher from windows to mac and i can't live without maple. but when i want to superscript for example x^2 in maple it shows me x ^ 2, so i can't solve a function that easily, because the superscript isn't accepted. but when i copy the caret out of an predesigned example it works fine. do you can tell me how i have to set my preferences that it works as easy as it does on windows? i hope you understand my problem and i hope that you can excuse my bad english! with kind regards, max pfister
I need to find the trace of a matrix A. What is the command for that? I can't find it in maple's help. (I'm using Maple10 if that changes the answer) Thank you!

I was looking for a feature that would allow me to mark all the forums "as read" and a way of then loggin in to see what is new since I last logged in. Is there such a feature? Then I'd not have to scan all the posts to see what might be there since I last logged in. Rich
I am using the solve command in a proc to solve some simple equations. Is there an easy way of determining if the solution is an imaginary number? (basically I only want real solutions... sometimes the solutions will be in the form of a=b+1, i.e. in terms of another variable, and sometimes it will just be some number... once getting the solutions using something like ans:=solve(eqn,{vars}), how can I determine what type it is?

How do i find a background curve to a graph, i have data fitted with a spline and i need to find the background curve
For example, I type in standard F=ma 5 kg * 1 m/ s^2 Maple 10 spits this back after the = as 5kg*m/s^2 rather than the more common 5 kg*m/s^2 with the divisor sign half way down the 5. And what I really want is to be able to ask for any compatible units, in this case, N for Newtons, and have N replace kg*m/s^2. I notice that there is a new [[]] format for units. When I use them, they appear in my document, not all what I'd expect. Thanks much, Rich
I'd like to have the ability to change, say, 12345.678 to Engineering 12.345E+03 12.345x10^3 Scientific 1.234E+04 1.23456x10^4 General/decimal 12345.6 fraction of varying size Are these possible? I have tried with no success... Thanks, Rich
