## Solving ODE in Maple...

Maple

Hi Guys,

I am trying to solve the folling ODE in maple but am struggling to get to the correct solution. I first of all have the following equations;

Which give me the following;

With thw boundary conditions;

M(l) = 0, M(0) = 0, v(0) = 0, v(l) = 0

The given solution is;

v(x)=(qx/24EI)*(x^3-2lx^2+l^3)

Anything that might point me in the right direction would be great!

Cheers

## Fitting constants to equation...

Maple

Hi guys,

I am trying to fit some constants to an equation in maple but am very new to the software and am struggling somewhat to input he correct commands.

I have the following equation;

x=a(y^b)(z^c)

And I have data points for x, y and z

I need to calculate the best fit value for a, b and c based on this data.

These constants are material properties for calculating creep in a structures and the data is somewhat dirty, therefore my hand calcs lead to an unsolvable results so best fit values are my only hope!

Any suggestions or a nudge in the right direction would be wonderful!

Thanks

Steve
