# rationalize

1. ### Enter the exact answer as a single fraction. Rationalize the denominator, if required

cos(cos-13/4+tan-13) Enter the exact answer as a single fraction. Rationalize the denominator, if required
2. ### 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?
3. ### Rationalize the Numerator

Please help me rationalize the numerator of this problem The back of the book answer is I have tried but cannot seem to get the answer. I believe I am having a simplifying problem, but if anyone can show me steps, that would be highly appreciated.
4. ### 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...

Find the point on the graph at which the slope of the tangent line is the given number m. y = a cube root of x; m = 6
6. ### Rationalize a fraction with fractional exponent

My question is, how are they getting from step 2 to step 3. Where is the 3^4/5 coming from?! Not sure i understand the rationalize the denominator of (1/3)^1/5 Thanks for the help.
7. ### 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'...
8. ### Question about rationalizing equations

Hey, I have a question: Is there currently an existing equation that would rationalize 1/(a'th root of x + b'th root of y)? If so, what is it? Thanks, Robbie
9. ### Rationalize the Denominator

I can't seem to solve this one. I tried reversing the signs, which didn't work for me. How do I solve this one?
