What is the area under the curve in the interval [2,7] for the function #1/(1 + x^2)^(1/2) #? Calculus Introduction to Integration Integration: the Area Problem 1 Answer dani83 Aug 19, 2015 # int_2^7 1/sqrt(1+x^2) dx = sinh^-1 (7)- sinh^-1 (2) = 1.20 # (3sf) Explanation: # int_2^7 1/sqrt(1+x^2) dx = sinh^(-1) x|_2^7 = sinh^-1 (7)- sinh^-1 (2) # Answer link Related questions How do you find the area of a region using integration?
