Short Answer

Use a sentence to describe what the notation $\sum_{k = 2}^{100} \sqrt{k}$ means. (Hint: Start with “The sum of....”)

Step 1. Given Information:

Given sigma notation: $\sum_{k = 2}^{100} \sqrt{k}$

Use a sentence we want to describe what the notation means.

Step 2. Solution:

First we write notation in expand form we get

$\sum_{k = 2}^{100} \sqrt{k} = \sqrt{2} + \sqrt{3} + \sqrt{4} + . . . . . + \sqrt{100}$

We observe that given notation represents:

The sum of square roots of 2 to 100.

If $\int_{- 2}^{3} f (x) d x = 4, \int_{- 2}^{6} f (x) d x = 9, \int_{- 2}^{3} g (x) d x = 2$ , and $\int_{3}^{6} g (x) d x = 3$ , then find the values of each definite integral in Exercises $29 - 40$ . If there is not enough information, explain why.

$\int_{- 2}^{- 2} x (f (x) + 3)^{2} d x$

Without using absolute values, how many definite integrals would we need in order to calculate the area between the graphs of f(x) = sin x and g(x) = $\frac{1}{2}$ on $[- \frac{π}{2}, 2 π]$ ?

Suppose f is positive on (−∞, −1] and [2,∞) and negative on the interval [−1, 2]. Write (a) the signed area and (b) the absolute area between the graph of f and the x-axis on [−3, 4] in terms of definite integrals that do not involve absolute values.

Use the Fundamental Theorem of Calculus to find the exact values of the given definite integrals. Use a graph to check your answer.

$\int_{0}^{1 / 2} \frac{1}{1 + 4 x^{2}} d x$

Use integration formulas to solve each integral in Exercises 21–62. You may have to use algebra, educated guess- and- check, and/or recognize an integrand as the result of a product, quotient, or chain rule calculation. Check each of your answers by differentiating. (Hint for Exercise 54: $\tan (x) = \frac{\sin (x)}{\cos (x)}$ ).

$\int \frac{e^{3 x} - 2 e^{4 x}}{e^{2 x}} d x$ .
