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.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
