Help with cal 2 exercise involving integrals?I have to find the arc length of y = lnx given that 1 ≤ x ≤ sqrt (3) Here is my procedure: I found the derivative of y = lnx And got, y' = 1 / (x) 1 + (1/(x))^2 = 1 + (1/(x^2)) = (x^2+1)/(x^2) integral from 1 to sqrt 3 of sqrt((x^2+1/(x^2)) dx = sqrt ( x ^ 2 + 1 ) / ( x ) dx X = tan b Dx = (sec^2)BdB Sqrt(x^2+1) = Sqrt ( (tan^2)B + 1) = Sqrt ( (Sec^2)B) = SecB Integral = ((sec)/(tanB)) times (sec^2)BdB And here comes the part I don't understand, in my exercise it becomes Integral = ((sec^2)B)/((tan^2)B)) times secBtanBdB Why did this happen, please help me figure out how.
