QUESTIONS - ANSWERS - SHERILL - INTEGRATION


sherill has left a new comment on your post "QUESTIONS - CDOG - VECTORS":

Please find the area between the two curves f(x)=1/(x+2) and g(x)=e^x over the interval [0,1]

AREA = INTEGRAL 0 TO 1 [ E^X - {1/(X+2)}]=[E^X - LN(X+2)] FROM 0 TO 1
=E-LN(3)-1+LN(2)=E-1-LN(1.5)
