How can I plot f(x,y)=(cos(x^2+y^2))^1/2 whithout knowing the domain?

And then having Maple to find the domain and plot it?

Thanks.

hello,

I have a .txt file with 1000 lines of data.

This data was collected from an electronic compass located in a car moving in different directions.

Each line was written in function of time,every 0.1s.

Each line has 4 columns, and each column represents a cardinal point.

1st column--->North, 2nd column--->East, 3rd Column South---> 4th column West

768------768------768------2

768------768------768------2…

I want to find (-8sqrt(2)-8sqrt(2)i)^(1/4),

I solve it and I got this answers in polar form. (4,5PI/16) (4,13Pi/16) (4,21Pi/16) and (4,29Pi/16)

I tried this in maple, but it didn´t work. z:=((-8*sqrt(2)-8*sqrt(2)*I))^(1/4) ; ec:=convert(z,'RootOf'); allvalues(ec);

 

Thanks.

(i^1)*(i^2)*(i^3)....*(i^2010)=

 

Thanks

I want to plot this graph with maple. http://img843.imageshack.us/img843/5300/graphh.jpg The lines are: a) x=2t+3; y=5t-2; z=-t+1 b) x=-2t+7; y=t+8; z=2t-1. I tried to plot the first line with spacecurve, but I don't now how to plot the two lines together.Also I couldn't plot the z axes in the vertical position. spacecurve([2*t+3,5*t-2,-t+1],t=-10..10,axes=normal, labels=[x,y,z],scaling=constrained); Is there a way to find and represent on the intersecting...
