Solving Taylor Series: Discover the Function Behind this Tricky Sequence

Click For Summary
SUMMARY

The discussion centers on identifying the function that generates the series: (\pi^2/(22)) - (\pi^4/(24*3!)) + (\pi^6/(26*5!)) - (\pi^8/(28*7!)). Participants confirm that this series is related to the sine function, specifically the Taylor series expansion for sin(x). The final answer is established as sin(\pi/2), which equals 1, confirming the function's identity.

Homework Statement



What function produces the following:
([tex]\pi[/tex]2/(22)) - ([tex]\pi[/tex]4/(24*3!)) + ([tex]\pi[/tex]6/(26*5!)) - ([tex]\pi[/tex]8/(28*7!))

I'm sure this is a sin function.
But I can't figure out what exactly is the function.

Please help.

That can be written as

[tex]\pi/2[\pi/2 - (\pi/2)^3/3! + (\pi/2)^5/5! + ...][/tex]
 
Is that my final answer?
Or would sin(pi/2) be it?
