Hi,

I am trying to learn how to apply initial conditions to pdes with maple.  I have figured out how to do it with odes, but when assigning initial values to derivatives, I get weird results.  I have attached my Maple file, with the error, and a link to the document I am using as motivation for my analysis.

Hi,

I have made a maple file that is meant to test Maple's solution to the nonlinear pendulum equation.  I am doubtful that Maple is finding the correct solution.  Could someone comment on my analysis?

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.

Have a great day!Test_solve_for_x.mw
