Find the arclength of the curve , for .
I got this: r`(t) = <14t, 2sqrt(7), 1/t> , but I do not know how to integrate it's squareroot.
Please someone help me...
Do you know the formula for arclength when the curve is defined parametrically? Can you differentiate each component with respect to t? Can you substitute the derivatives into the formula and simplify?
Please show all the working you've been able to do and say where you get stuck.
