    Rationalize Denominator and Numerator

    Why do math teachers stress the process of rationalizing numerator and denominator? This is more a problem, I see, in terms of rationalizing the denominator. Why can't fractions have a radical in the denominator? What's the big deal?

    Rationalize the Following Antiderivative

    I need to use the some rationalizing substitution to get the following integral into a solvable form: Integral of dx/(sin(x) - cos(x) - 1) Wolfram Alpha said: For the integrand 1/(sin(x)-cos(x)-1), substitute u = tan(x/2) and du = 1/2 dx sec^2(x/2). Then transform the integrand using the...

    Rationalizing an equation?

    Hey, I already asked this question, but, as I was just learning how to use the site, I posted it in the wrong area, so it probably won't get an answer, so please forgive the repost. I was wondering, is there an equation that rationalizes 1/(a'th root of x+b'th root of y)? If so, what is it'...
