## Problem with Taylor series...

Maple

I am trying to do a taylor serie of a function but I recieved this error:

Error, (in Typesetting:-NeedsBrace) invalid input: the 1st argument to pointto is not a valid pointer handle

The aim of this is get the series to do its integration.

Thank you a lot for your responses.

## solution of differential equations...

Maple 2023

Good day to all the members who read this question.
I ask for your help to find the right way to solve this two differential equations (is attached the file). Used the common code "dsolve" but is not working on this problem. Doesn't matter if the solution is numeric or algebraic.
I will thaks a lot your kind help.
Best regards to all of you

The differential equation to solve:

Definitions:

Also I divided the differential equation in 3 parts (A, B, C).

## Plot using NLPSolve...

Maple

Good Day to all of you.

I am using the function NLPSolve to optimize a function and get its independent variable mínimum value. The problem is that is imposible to plot that Numbers because of the output way. Is like [5.02, [x=0.02]] and is imposible for my to graph.
The file is attached and also the code of someone tha did it in matlab, is exacly the same result i want to obtain.

I would be really thanks if someone can help me.
