Hi,

I am doing some work on differential equations, and I am checking the solutions.  Whether the solution is correct or not depends on whether or not a real number plus zero*i is a real number or an imaginary number.  I want to test how maple handles this by plotting sin(x)i. 

This is intended to be a complex plot.  I am expecting a series of points along the real axis where sin(x) is zero.  Can anyone help me with this?

 

Hi,

 

I want my vector field plot to have more arrows, and am wondering how to do this.  Here is the file:

Thanks in advance!

 

Hi!

I am double checking some textbook methods involving the arc length of a parabolic function of y.  I need to calculate the x coordinate that represents half the arc length of the parabola from x=0 to x=1

I have included my work in the form of a maple worksheet.  Help on this would be appreciated.

Hi,

Suppose I want to create a matrix of derivatives, like gradient, Hessian, or Jacobian, and then apply that matrix to a function.  How do I do this?

Thanks

Hi,

I am studying nonlinear differential equations, and I want to compare software that gives exact solutions to software that gives numerical solutions.

In the attached Maple document, I try to solve a nonlinear ordinary differential equation numerically, but it seems like the numerical solver cannot solve this type of nonlinear ODE.  Are there any numerical solvers in maple that can find a solution to this equation?
