## How to increase the number of arrows in ...

Maple 2019

Hi,

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

## Am I solving for x properly?...

Maple 2019

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.

## How to enter matrices of derivatives in ...

Maple

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

## Does Maple have a numerical method to so...

Maple

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?

Maple 2019

Hi,

I am studying nonlinear differential equations, and came across an interesting one on maple's help page.  I made a post about this equation already, but I have decided to make a new post because the topic is slightly different than from the previous post.

The topic of this post is:

"Can numerical methods and exact, implicit techniques find false solutions?"

To make the discussion clearer, the rest of this post can be found in the maple file I created.
