## Re: Symbolic operation using functions...

Hello there,

While I was trying to calculate the complex (i.e., P and Q) power equations, I got this question.

Thus, I wonder if I can have a chance to ask the question here:

a. When the voltage and current are defined as functions, taking the t (time) as a input variable, I was not able to get the proper outcome from the operation. Those attempts are labeled as '#1' and '#2' in the attached worksheet.

b. When the voltage and current are defined as simple complex expression, I was able to see what I wanted. The expression is named as 'ideal' in the attached worksheet.

c. Therefore, my question is to see if there is a way to make the operaion using the functions in the same way as done by the simple expressions.

d. Any insight would be appreciated.

Thank you.

## Maple unable to evaluate integral but upon simple ...

So Maple 2019 seems to be unable to evaluate a relatively easy integeral for a positive integer, but when the obvious substitution u=cos(x) is made it is able to evaluate the integral.  Is there some setting I am using that is causing Maple to give up without much effort?

## Getting to Know Maple Coming from a Programming Ba...

I am brand new to Maple, both as a specific program and as an example of symbolic mathematical software (although years ago I spent some time with MathCad).

I am interested in referrals to online resources which can help me progress down the learning curve. I have a substantial background in application computer programming, mostly in C#.

So if there's such a thing as "Maple for Programmers" that might be ideal...particularly since I find Maple's syntax and semantics to be "just similar enough" to coding that it causes me a lot of frustration. As in, simply entering the examples from the online manual Just Doesn't Work :).

Thanx!

Hi everyone, i'm working on a project and i'm having a problem as such:

I got t1 already (t1=26,88) by solving s(t)=0 and when I try to calculate s(t) with t=t1, i type s(t1) Maple give me 1.10^(-6) as result but the result should be 0.22144. Here are my codes:
