# Compute an approximate value of an integral

Posted by Mathoman, Wednesday 16 June 2010 at 20:05 - Riddles And Exercises

A friend sent me a nice collection of exercises about which I will talk soon on this blog. One of the questions is simply:

Calculate the mean value of sin^{100}(x) with a precision of 10%.

I suppose that one must understand calculate the mean value on an interval having the length of a period (for example between 0 and pi).

According to the author of the list of exercises a student who is unable to solve this problem within five minutes does not master mathematics at all... What about you? :-)

To close this entry here are two nice math sentences:

To speak algebraically, Mr. M. is execrable, but Mr. G. is(x+1)ecrable.â€” Edgar Alan Poe

Even the strongest number needs its zeros:100000000.
