A long time has passed and i thank you for this! However, i was wondering how you calculated the maximum, by paper or by some digital tool? We are allowed to use Wolframalpha and i have inserted all of it in there but i do not recieve the same results as you do!!!
d((10-tan??(22°)x-3 tan?(22°) ?)/x +(tan??(22°)x-3 tan?(22°) ?-2)/x)/(1-((10-tan??(22°)x-3 tan?(22°) ?)/x)( (tan??(22°)x-3 tan?(22°) ?-2)/x))/dx=0 - Wolfram|Alpha
Please take a look at the link.

Good evening and happy Easter,
as far as I can see your input-line is incorrect: You must put the term into parantheses representing y.
y consists of 3 summands but you have suppressed the +1 .
I don't understand why there are so many question marks in your input-line.
And I'm not familiar with Wolfram Alpha
Hello,
since you only can get approximate values I used approximate values from the beginning. It means that you have to type in a lot of cyphers but on the other hand it reduces processing time of the computer. And of course I do not do these calculations by hand.
I've attached a protocol which is generated by the math program I use. Only the comments are added. Hopefully this will show you how I did your question.
I use derive 6.0. This program is very old, there aren't any updates available but I know how to use it and it works fine for me.
If you use the approximate values even Wolfram Alpha will do the job. Have a look here:

2nd approach: I finally learned how to place an active link in this post.
