Find the are under the given curve

y=square root of x + 1
from x=0 to x=9

Please walk me through each step.

  • math calculus -

    Do you mean sqrt(x+1) or sqrt x + 1?

    If the former, the indefinite integral is [(x+1)^3/2]/(3/2)
    Evaluate it at x = 9 and x = 0 and take the difference.

    Area = (2/3)*[(10)^(3/2) - 1]
