# Another derivative confirmation.

• Sakha
In summary, the conversation discusses finding the derivative of a given function using algebra and online calculators such as Mathematica and WolframAlpha. The solution is provided and a request is made for confirmation and suggestions for an online calculator to verify the solution.

## Homework Statement

Find the derivative of:
f(x)= ((x+xsinx)/(1+2tan2x))3

## The Attempt at a Solution

I solved it and got :
f'(x)= (3(1+2tan2x)3(x+xsinx)2(sinx+xcosx+1)-12(x+xsinx)3(2tan2x+1)2(tanxsec2x))/(1+2tan2x)6

Can anyone confirm if this is alright?
Also, anyone knows a webpage that has an online calculator that would confirm this kind of math problems?
Thanks.

Here's what I got in Mathematica, I'm too lazy to do the algebra to compare. See attachment. Btw, Sec(x) = 1 / Cos(x).

I'm more than lazy to do this algebra. There has to be a way of comparing answers in WolframAlpha's Mathematica.

You also use Wolframalpha.com if you don't have Mathematica. See here.

What I meant is that there has to be some feature in WolframAlpha to compare functions and see if they are algebraically equal. Like comparing Mathematica's answer to my derivative, to my derivative.

Perhaps plugging in a few specific values into both and seeing what happens would suffice? Or don't be lazy The algebra doen't look that bad.

## 1. What is another derivative confirmation?

Another derivative confirmation is a method used by scientists to confirm the results of previous experiments or studies, typically with a different approach or technique.

## 2. Why is another derivative confirmation important?

Another derivative confirmation is important because it helps to validate the accuracy and reliability of scientific findings. It can also provide additional evidence to support a hypothesis or theory.

## 3. How does another derivative confirmation differ from replication?

While replication involves repeating an experiment or study exactly as it was originally conducted, another derivative confirmation involves using a different method or approach to reach the same conclusion.

## 4. What are the benefits of using another derivative confirmation?

Using another derivative confirmation can help to strengthen the validity of scientific findings by providing additional evidence. It can also help to identify any potential flaws or limitations in the original study.

## 5. Can another derivative confirmation be used in all scientific fields?

Yes, another derivative confirmation can be used in all scientific fields. It is a common practice in many areas of science, including biology, chemistry, physics, and psychology.
