binary floating point perform substraction and addition if $x=1.0e38=1.0 * 10^{38}$ and $y=3.0$ i want to find $ (x-x)+y $ and $(x+y)-x$ i think the value of (x-x)+y will be just substract $x-x=0 + y=3.0 = 3.0$ ...

You have to define what floating point format you are using. Standard IEEE $64-$bit floating point assigns $53$ bits to the mantissa, giving a precision of about $16$ decimal digits. $10^{38}$ will be represented by some $53$ bit mantissa times a binary exponent. To add to that, you have to match th...

Consider for a fixed value of $x$ which ca n varies from $x = 0$ to $x = 1$. In between $0$ and $1$, the courses form a triangle with height and base length calculated as below. $$z = xy$$ $$y + z = 1 - x$$ Solving this equations we have $$y = \frac{1 - x}{1 + x}$$ $$z = \frac{x(1 - x)}{1 + x}$$ The...

Percentage + abstract/substract question ![]( My calculation was (55205845)31% and I got value 10,001,964. Closest answer is 10,100,000. Is the answer right? Thanks

No, the 5520*5845 gives the number of good units produced. This is 69% of the total. The rejection is 31% of the total.

Continuity of a complex function Show that $f(z)=xy+iy$ is everywhere continuous but is not analytic. We have $\displaystyle w=f(z)=u(x,y)+iv(x,y)$ and $\displaystyle z=x+iy$. Do I just say that as both u and v her...

Observing that they are each polynomials is enough to see that the function is continuous in each variable separately but not necessarily that it is continuous. (You probably saw examples in Calc III where a function was not continuous at the origin even though it was continuous in each variable sep...

Find a and b such that this limit is equal to an answer. $\lim_{n\rightarrow\infty}(a+\frac{n+1}{bn^2+n+2})^{n+2}=\frac1e$ So I tried to get to the common denominator and then add 1 and substract 1 inside the power t...

Recall that the limit for $e^x$ is as follows: $$\lim_{n \to \infty} \left(1+{x \over n}\right)^{n}$$ So to achieve $\frac{1}{e}$, $x$ must be $-1$. You get this by using $a=1$ and $b=-1$ and factoring: $$\require{cancel} \lim_{n\rightarrow\infty}\left(1+\frac{n+1}{-n^2+n+2}\right)^{n+2}=\lim_{n\rig...

One dimension equivalent to area Some say that length is the $\mathbb R^1$ equivalent of $\mathbb R^2$ area or $\mathbb R^3$ volume but you can substract areas or have intersections of areas. I need to do the same in ...

What I was looking for was an Interval). I find the term way more intuitive and self descriptive than Length of even Measure. Thanks for the answers, but I'll stick with Interval. Edit: I was wrong, it's a collection of intervals and not a single interval.

Perl would be overkill here. find . -maxdepth 1 -mindepth 1 | wc -l (better use `grep -c /` instead of `wc -l` in case some filenames have newline characters in them). Or with GNU `ls`: ls -A | wc -l With `zsh`: f=(*(D)) echo $#f To remove one: ... | tail -n +2 | wc -l Or: n=$(... | wc -l); echo "$(...

Properties of Cardinality and intersection I have three sets A, B and C satisfying the following conditions: * $ \\#(A\cap B) = 11$ * $ \\#(A\cap C) = 12$ * $ \\#(A\cap B\cap C) = 5$ What is the minimun cardina...

\begin{align} \\#(A\cap (B\cup C)) &= \\#((A\cap B)\cup (A\cap C))\\\ &=\\#(A\cap B)+\\#(A\cap C)-\\#(A\cap B\cap C)\\\ &=11+12-5=18. \end{align} Note that $A$ cannot be fewer than $18$ since $A\cap(B\cup C)\subseteq A$, thus $\\#(A)\geq18$. Now, if we can find an example, where $\\#(A)=18$, we'll h...

Since you’re using double quotes, the shell interprets `$1` and `$2`, replacing them with the first two arguments in the current context (so probably the empty string in both cases, given the error you’re getting). You should use single quotes: awk '{ print $1-$2; }'

Let $\frac{1}{5}=x$ and $f(x)=x+\frac{1}{3}x^3+\frac{1}{5}x^5+...$ Thus, $$f'(x)=1+x^2+x^4+...=\frac{1}{1-x^2}$$ and $$f(x)=\int\limits_0^x\frac{1}{1-t^2}dt=\ln\sqrt{\frac{1+x}{1-x}},$$ which after substitution $x=\frac{1}{5}$ gives the answer: $$\frac{1}{2}\ln1.5.$$

Take $x^2+5x+2=y^2$ for some integer $y$. Then from the quadratic formula, we know that $$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$$ $$x=\dfrac{-5\pm\sqrt{5^2-4(2-y^2)}}{2}=\dfrac{-5\pm\sqrt{25-8+4y^2)}}{2}=\dfrac{-5\pm\sqrt{17+4y^2)}}{2}$$ Now, for $x$ to be an integer, $4y^2+17$ should be a perfect squar...

Not a radical ideal Is there a method to compute the radical of an ideal? for example take $J=(xw-y^{2},xw^{2}-z^{3}) \subset k[x,y,z,w]$. I want to show $J$ is not radical, I guess the idea is to add and substract te...

I think your ideal is radical. To prove that, you can compute the singular locus of the associated variety, using jacobian criterion. If its codimension at each point is at least one, then your variety is reduced, and hence your ideal is radical. All these computation can be done with a commutative ...

The equation of the tangent line to the graph of a function $y=f(x)$ through the point $(x_0,f(x_0))$ is given by $y=f'(x_0)(x-x_0)+f(x_0).$
