Find the derivative with respect to x of the integral from 2 to x^3 of ln(x^2)dx

strojnjashka [21]

The derivative follows from the fundamental theorem of calculus:

$\displaystyle\frac{\mathrm d}{\mathrm dx}\int_c^{g(x)}f(t)\,\mathrm dt=f(g(x))\dfrac{\mathrm dg}{\mathrm dx}$

where $c$ is any constant in the domain of $f$ .

We have

$g(x)=x^3\implies\dfrac{\mathrm dg}{\mathrm dx}=3x^2$

$\displaystyle\frac{\mathrm d}{\mathrm dx}\int_2^{x^3}\ln(t^2)\,\mathrm dt=3x^2\ln((x^3)^2)=18x^2\ln x$

(applying the property $\ln a^b=b\ln a$ )

For which values of a the system 3−7x < 3x−7 ,1+2x < a+x has no solutions?

erica [24]

Answer:

a= -infinity to 3

Step-by-step explanation:

Given

$3 - 7x < 3x - 7$

$1+2x < a+x$

Required

Determine the value of a such that the inequality has no solution

Considering the first inequality (Solve for x):

$3 - 7x < 3x - 7$

Collect Like Terms

$3 + 7 < 3x + 7x$

$10 < 10x$

Divide both sides by 10

$1 < x$

Reorder

$x > 1$

This means that the least value of x is 2;

Substitute $x=2$ in the second equation

$1+2x < a+x$

$1 + 2(2) < a + 2$

$1 + 4 < a + 2$

$5 < a + 2$

Collect Like Terms

$5 - 2 < a$

$3 < a$

Reorder

$a > 3$

This means that the least value of a is 4

Hence;

The values of a for which the system has no solution is -infinity to 3
