Example Question #73 : Finding Integrals

Evaluate.

$\int_{1}^{2} \cos (2x) - \frac{1}{2x} \ dx$

Possible Answers:

-1.18

6.22

1.35

-4.35

Answer not listed.

Correct answer:

-1.18

Explanation:

$\int_{a}^{b} f(x) dx$

In order to evaluate this integral, first find the antiderivative of f(x).

In this case, $f(x) = \cos (2x) - \frac{1}{2x}$ .

The antiderivative is $F(x) = \frac{ \sin(2x)}{2} - \frac{\ln(2x)}{2}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{1}^{2} \cos (2x) - \frac{1}{2x} \ dx = \left ( \frac{ \sin(2x)}{2} - \frac{\ln(2x)}{2} \right )_{1}^{2}$

$= \frac{ \sin(2(2))}{2} - \frac{\ln(2(2))}{2} - \left ( \frac{ \sin(2(1))}{2} - \frac{\ln(2(1))}{2} \right )$

= -1.18

Example Question #61 : Definite Integrals

Evaluate.

$\int_{1}^{2} 2x + 3x^2 + 4x^3 \ dx$

Possible Answers:

Answer not listed.

Correct answer:

Explanation:

$\int_{a}^{b} f(x) dx$

In order to evaluate this integral, first find the antiderivative of f(x).

In this case, f(x) = 2x + 3x^2 + 4x^3 .

The antiderivative is F(x) =x^2 + x^3 + x^4 .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{1}^{2} 2x + 3x^2 + 4x^3 \ dx = \left ( x^2 + x^3 + x^4 \right )_{1}^{2}$

$=(2)^2 + (2)^3 + (2)^4 - \left ( (1)^2 + (1)^3 + (1)^4 \right )$

= 25

Correct answer:

4102

Explanation:

$\int_{a}^{b} f(x) dx$

In this case, $f(x) = 3x^2 + 12x^{11}$ .

The antiderivative is $F(x) = x^3 + x^{12}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{1}^{2} 3x^2 + 12x^{11} \ dx = \left ( x^3 + x^{12} \right )_{1}^{2}$

$= (2)^3 + (2)^{12} - \left ( (1)^3 + (1)^{12} \right )$

1.81

Answer not listed.

Correct answer:

1.81

Explanation:

$\int_{a}^{b} f(x) dx$

In this case, $f(x) = e^{4x- 2}$ .

The antiderivative is $F(x) = \frac{e^{4x- 2} }{4}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{0}^{1} e^{4x- 2} \ dx = \left ( \frac{e^{4x- 2} }{4} \right )_{0}^{1}$

$= \frac{e^{4(1)- 2} }{4} - \left ( \frac{e^{4(0)- 2} }{4} \right )$

= 1.81

0.93

0.26

Answer not listed.

Correct answer:

0.26

Explanation:

$\int_{a}^{b} f(x) dx$

In this case, $f(x) = \frac{1}{9x-8}$ .

The antiderivative is $F(x) = \frac{\ln (9x-8)}{9}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{1}^{2}\frac{1}{9x-8} \ dx = \left ( \frac{\ln (9x-8)}{9} \right )_{1}^{2}$

$= \frac{\ln (9(2)-8)}{9} - \left ( \frac{\ln (9(1)-8)}{9} \right )$

= 0.26

Evaluate.

$\int_{0}^{\frac{\pi}{2}} -\cos(7x) \ dx$

Possible Answers:

$\frac{1}{2}$

$\frac{6}{7}$

$\frac{2}{3}$

$-\frac{1}{7}$

Answer not listed.

Correct answer:

$-\frac{1}{7}$

Explanation:

$\int_{a}^{b} f(x) dx$

In this case, $f(x) =-\cos(7x)$ .

The antiderivative is $F(x) = - \frac{\sin(7x)}{7}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{0}^{\frac{\pi}{2}} -\cos(7x) \ dx = \left ( - \frac{\sin(7x)}{7} \right )_{0}^{\frac{\pi}{2}}$

$= - \frac{\sin(7(\frac{\pi}{2}))}{7} - \left ( - \frac{\sin(7(0))}{7} \right )$

$= -\frac{1}{7}$

The antiderivative is $F(x) = \frac{e^{2x-5}}{2} + \frac{\cos(2x-5)}{2}$ .

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{3}^{4}{} e^{2x-5} - \sin(2x-5) \ dx = \left ( \frac{e^{2x-5}}{2} + \frac{\cos(2x-5)}{2} \right )_{3}^{4}$

$= \frac{e^{2(4)-5}}{2} + \frac{\cos(2(4)-5)}{2} - \left ( \frac{e^{2(3)-5}}{2} + \frac{\cos(2(3)-5)}{2} \right )$

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{1}^{2}5x^4 + 12x \ dx = \left ( x^5 + 6x^2 \right )_{1}^{2}$

$= (2)^5 + 6(2)^2 - \left ( (1)^5 + 6(1)^2 \right )$

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:

$\int_{2}^{3}\frac{4}{x-1} \ dx = \left ( 4 \ln(x-1) \right )_{2}^{3}$

$= 4 \ln(3-1) - \left ( 4 \ln(2-1) \right )$
