14. 2057 Q.No. 1(a) Sum to infinity:<br>1 + 3x + 5x2 + 7x3 +... (-1<x<1).

aleksandrvk [35]

The sum appears to be

$\displaystyle\sum_{n=0}^\infty(2n+1)x^n$

I'll assume you want to find out what function this sum converges to.

Let

$f(x)=\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n$

with -1 < <em>x</em> < 1. Differentiating gives

$f'(x)=\dfrac1{(1-x)^2}=\displaystyle\sum_{n=0}^\infty nx^{n-1}=\sum_{n=1}^\infty nx^{n-1}=\sum_{n=0}^\infty(n+1)x^n$

So we have

$\displaystyle\sum_{n=0}^\infty(2n+1)x^n=f'(x)+xf'(x)$

$\displaystyle\sum_{n=0}^\infty(2n+1)x^n=\frac{1+x}{(1-x)^2}$

The slope of the line below is 4 . Which of the following is the point slope form of that line ? ( top answer gets )

Zanzabum

Answer:

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 4 and (a, b) = (- 3, - 4) , thus

y - (- 4) = 4(x - (- 3)) , that is

y + 4 = 4(x + 3) → C
