    Approximating PI: Int. of x^4(1-x)^4/(1+x^2)= 22/7 - Pi

    Thanks, I got it. Don't know why I didin't see it earlier. Now if I had to find the maximum of the numerator, how would I go about using it to show that \frac{22}{7}<\frac{\pi}{1024}<\frac{1}{100} and how does it imply that the approximation \frac{22}{7}is accurate to 2 decimal places? I know...

    Approximating PI: Int. of x^4(1-x)^4/(1+x^2)= 22/7 - Pi

    Approximating PI Show that \int\stackrel{1}{0}\frac{x^{4}(1-x)^{4}}{1+x^{2}}dx=\frac{22}{7}-\Pi Why does this imply that \Pi\triangleleft\frac{22}{7} I have no clue where to begin with this, I'm at a loss, this is one of the questions for in my university project, first year. Any help is...
