Express the limit as a definite integral on the given interval. lim n→∞ n xi ln(2 + xi2) δx, [0, 3] i = 1

The given expression is:

This expressions represent the sum of certain numbers of rectangles that comprehend the area under a curve, where the number of rectangles tend to infinite. Actually, this definition states that when tend to infinite, there's the area under the curve.

However, this can be expresses as a definite integral, which tend to have more sense for students:

With the integral form can be shown better what we tried to say before. The integral represents the area under the given function , but just the part inside the interval from 0 to 3. The limit also refers to this, but in a different notation.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

i believe the answer is the polygon, heptagon.
