Yes. Your argument is valid. In a nutshell, your argument is this: Take any $f \in X^*$. Since $X$ is finite dimensional, $f$ is bounded. So, $f \in X'$. So, $X^* \subseteq X'$, as desired. When $X$ is infinite dimensional, we can always construct an unbou... | |

Sequence of Interpolating Values
Hero
New member
Construct a sequence of interpolating values $$y_n$$ to $$f(1 +\sqrt{10})$$, where $$f(x)= \frac{1}{1+x^2 }$$ for $$−5≤x≤5$$, as follows: For each $$n = 1,2,…,10$$, let $$h =\frac{10}{n}$$ and $$y_n= P_n (1+\sqrt{10})$$, where $$P_n(x)$$ is the interpolating polynomial... | |

# How do you solve y^2+y=20?
Dec 21, 2017
${y}^{2} + y = 20$
${y}^{2} + y - 20 = 0$
What $2$ numbers add to $+ 1$ and multiply to $- 20$?
$+ 5$ and $- 4$.
Therefore,
$\left(y + 5\right) \left(y - 4\right) = 20$
Therefore, $y$ can be color(red)(-5 or, +4
Dec 21, 2017
$y = - 5 , 4$

Question from Michael: Find the Quotient: ((a-5)/a)/(4/a)
Hi Michael,
If $a = 0$ the expression
$\frac{\frac{a-5}{a}}{\frac{4}{a}}$
is undefined. If $a \ne 0$ I would multiply the numerator and denominator by $a.$
