Here you can keep your brain fit by solving math related problems and also earn SBI or sometimes other rewards by doing so.
The problems usually contain a mathematical equation that in my opinion is fun to solve or has an interesting solution.
I will also only choose problems that can be solved without additional tools(at least not if you can calculate basic stuff in your head), so don't grab your calculator, you won't need it.
No upvote, No resteem, No follow required!
I will give the SBI(s) randomly to any participants.
You have 4 days to solve it.
Today I want to try something different: A proof.
Snice I don't know how much experience you have in mathematical proofs I will ignore small logical or syntactical errors in prize distribution.
Proof to me that euler's formula is true:
Tip: You might want to take a look at taylor series.
To everyone who already participated in a past contest, come back today and try a new problem(tell me if you don't want to be tagged):
@addax @ajayyy @athunderstruck @bwar @contrabourdon @crokkon @fullcoverbetting @golddeck @heraclio @hokkaido @iampolite @kaeserotor @masoom @mmunited @mobi72 @mytechtrail @ninahaskin @onecent @rxhector @sidekickmatt @sparkesy43 @syalla @tonimontana @vote-transfer @zuerich
In case no one gets a result(which I doubt), I will give away the prize to anyone who comments.
