From Google News Search: "sqrt" What is 2 to the sqrt of 7 times 2 to the sqrt of 7? Q. What is.. 2sqrt7 times 2sqrt7 In case you're having trouble following me.. 2 is on the outside of the square root sign, 7 is on the inside. Multiply them together. Please tell me how you did it. Asked by The Saints - Tue May 26 20:33:37 2009 - - 4 Answers - 0 Comments A. Saying 2sqrt7 is like saying 2 x sqrt7. So: (2 x sqrt7) x (2 x sqrt7) Just get rid of the parentheses. 2 x 2 x sqrt7 x sqrt7 4 x 7 28 Answered by ? - Tue May 26 20:37:29 2009 How do I evaluate the integral 1/sqrt[4+(x^2)] on the interval [0, 2]? Q. According to the book, the answer is arcsinh 1 = ~0.8814. I can't seem to figure out how to arrive at this answer though. Any suggestions? Thanks a bunch!! :) Asked by Aimee - Thu Jul 10 09:14:44 2008 - - 1 Answers - 0 Comments A. Okay, I'll do this for you. I was waiting to see if anyone else would do it, but it doesn't seem like it. And I just really really hate calculating integrals, so you should feel lucky I'm going to do it for you lol Here it goes: dx/ (4 + x ) I'm going to do a hyperbolic substitution: Let x = 2sinh(y) Then we have that: dx = 2cosh(y)dy After the substitutions, your integral becomes: dx/ (4 + x ) = 2cosh(y)dy/ (4 + [2sinh(y)] ) = 2cosh(y)dy/ (4 + 4sinh (y)) = 2cosh(y)dy/ (4[1 + sinh (y)]) = 2cosh(y)dy/ (4cosh (y)); because cosh (y) - 1 = sinh (y) = 2cosh(y)dy/2cosh(y) = dy = y But we have that: x = 2sinh(y) x/2 = sinh(y) arsinh(x/2) = arsinh(sinh(y)) arsinh(x/2) = y Therefore, your integral is: dx/ (4 + x… [cont.] Answered by Buri - Thu Jul 10 10:11:11 2008 How to find the integral from 2 to 4 of sqrt[1+(x-[1/(4x)])^2] dx?
