2) - (-4+5i)=4-5i
3) 1/(2+i)=(2-i)/(4+1) = (2-i)/5
4)1/(-3+5i)=(-3-5i)/(9+25)
5) square root of ( 5*5 + 12*12) = 13

Use the power series for 1 1−x to find a power series representation of f(x) = ln(1−x). What is the radius of convergence? (Note
Viktor [21]

a. Recall that

\displaystyle\int\frac{\mathrm dx}{1-x}=-\ln|1-x|+C

For |x|, we have

\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n

By integrating both sides, we get

\displaystyle-\ln(1-x)=C+\sum_{n=0}^\infty\frac{x^{n+1}}{n+1}

If x=0, then

\displaystyle-\ln1=C+\sum_{n=0}^\infty\frac{0^{n+1}}{n+1}\implies 0=C+0\implies C=0

so that

\displaystyle\ln(1-x)=-\sum_{n=0}^\infty\frac{x^{n+1}}{n+1}

We can shift the index to simplify the sum slightly.

\displaystyle\ln(1-x)=-\sum_{n=1}^\infty\frac{x^n}n

b. The power series for x\ln(1-x) can be obtained simply by multiplying both sides of the series above by x.

\displaystyle x\ln(1-x)=-\sum_{n=1}^\infty\frac{x^{n+1}}n

c. We have

\ln2=-\dfrac\ln12=-\ln\left(1-\dfrac12\right)

\displaystyle\implies\ln2=\sum_{n=1}^\infty\frac1{n2^n}

Write the equation of the line that passes through (−1, 5) and has a slope of 3 in point-slope form. (2 points)
aleksandr82 [10.1K]
The point-slope form: y-y_0=m(x-x_0)

m = 3; (-1; 5) \to x_0=-1;\ y_0=5

subtitute

y - 5 = 3(x - (-1))

y - 5 = 3(x + 1)
