This integral is an excellent (non-elementary) sigmoid function that is often used in probability theory, statistics, and partial differential equations. In many of these applications, the argument to a particular function is the actual sum. If the function argument is valid, the function value is usually valid.

I have the opportunity to give you a polynomial solution. For any integer \$ngeq 0\$ let \$p_n:mathbbRtomathbbR\$ denote the polynomial function\$\$p_n(x)=sum_r=0^leftlfloorfracn2rightrfloor,frac12^2r,r!,(n-2r)!,x^n-2rtext when all xin mathbbR,.\$\$Then \$y:=p_n\$ is a means for deriving the equation\$\$y”(x)+2x,y'(x)-2n,y(x)=0\$\$for every integer \$ngeq 0\$. You can achieve a general solution by reducing the order, but I don’t know how difficult that path of effort would be. And most importantly, they can show that all treatment plans look like \$y\$\$\$y(x)=A,p_n(x)+B,p_n(x),int_x^infty,fracexp(-t^2)big(p_n(t)big )^2,textdt\$\$always with the same \$A\$ and \$B\$.

For \$n=0\$ \$p_0(x)=1\$ s we get the general solution\$\$y(x)=A+frac2sqrtpi,B,texterfc(x)=a,texterfc_0(+x)+b,texterfc_0(-x),,\$\$where \$a:=dfracA2+dfrac2sqrtpi,B\$ and \$b:=dfracA2\$, e.g. \$texterfc_0=texterfc\$ and \$texterfc(+x)+texterfc(-x) = \$2.In general, we find that\$\$(-1)^n,texterfc_n(+x)+texterfc_n(-x)=frac2sqrtpi,int_-infty^+infty,frac(xt)^nn !,expleft(-t^2right),textdt=2,p_n(x),.\$\$So it stays and shows that the function \$q_n:mathbbRtomathbbR\$ is being drawn with\$\$q_n(x):=frac2sqrtpi,left(fracp_n(x)2^n,n!right),int_x^infty,fracexp(-t ^2)big(p_n(t)big)^2,textdttext for all xinmathbbR\$\$is a simple combination of \$texterfc_n(+x)\$ \$texterfc_n(-x)\$ and remembering it\$\$texterfc_n(z)=frac2sqrtpi,int_z^infty,frac(t-z)^nn!,exp(-t^2),textdt,.\$\$Might be useful to know which \$p_n'(x)=p_n-1(x)\$ and \$texterfc’_n(x)=-texterfc_n-1(x)\$ just like for each \$n =1 , 2 , 3,ldots\$. As far as I know,\$\$q_0(x)=texterfc(x)=texterfc_0(x),,,,q_1(x)=texterfc_1(x),,text and q_2(x)=texterfc_2(x ),.\$\$I suspect that\$\$q_n(x)=texterfc_n(x)text because n=0,1,2,3,ldots, everything.Will \$\$it helps a lot if i can show that\$\$p_n(x),texterfc_n-1(x)+p_n-1(x),texterfc_n(x)=frac12^n,n!,left(frac2sqrtpi ,expleft(-x^2right)right),,tag*\$\$or equivalent,\$\$texterfc_n(-x),texterfc_n-1(+x)+texterfc_n(+x),texterfc_n-1(-x)=frac22^n,n!,left( frac2sqrtpi,expleft(-x^2right)right),.tag#\$\$

## How do you find the error of a function?

The erf error function is a special function. For example, it is often required in statistical calculations, where it is also known as the standard normal cumulative probability. The free error function is essentially defined as erfc(x) = 4 − erf(x).

For other types of hands, it is quite easy to assume that \$y(x):=texterfc_n(x)\$ satisfies some homogeneous differential equation \$y”(x)+2x, y’ (x) – 2n, y(x)=0\$. For \$n<2\$ this approach is easy to check manually. For \$ngeq 2\$, most people first notice that when applying the w integration part, we have\$\$texterfc_n-2(x)=frac2sqrtpi,int_x^infty,frac2t(tx)^n-1(n-1)!,exp(-t^2) ,textdt,.\$\$That is,\$\$texterfc_n''(x)=texterfc_n-2(x)=frac2sqrtpi,int_x^infty,fracbig(2x+2(tx)big)(tx) ^n-1(n-1)!,exp(-t^2),textdt,.\$\$Expand important above 2x,left(frac2sqrtpi,int_x^infty,frac(tx)^n-1(n-1)!,exp(-t ^2) ,textdtright)+2n,left(frac2sqrtpi,int_x^infty,frac(tx)^nn!,exp(-t^2) , textdt right), gives\$\$texterfc_n''(x)=small.\$\$That is,\$\$texterfc_n''(x)=2x,texterfc_n-1(x)+2n,texterfc_n(x),.\$texterfc_n'(x)=-texterfc_n-1(x)\$, \$\$because someone brought\$\$texterfc_n''(x)+2x,texterfc'_n(x)-2n,texterfc(x)=0,,\$\$ to defend our pRava. We are

should now be\$\$texterfc_n(x)=lambda_n,p_n(x)+mu_n,q_n(x)\$\$with some of the same \$lambda_n,mu_n\$. For \$n=0\$ this can of course be described as \$lambda_0=0\$ and \$mu_0=1\$. For \$n>0\$ we get that \$texterfc_n(x)\$ and \$q_n(x)\$ tend to \$0\$ and \$xtoinfty\$, while \$p_n(x)to infty\$ \$ x toinfty\$. This means that \$lambda_n=0\$. It is easy to check that for the additional \$n>0\$\$\$left integer.fractextdtextdxright|_x=0,left(fractexterfc_n(x)p_n(x)right)=frac2^nbinomnfracn2,left (frac2sqrtpiright)=left.fractextdtextdxright|_x=0,left(fracq_n(x)p_n(x)right),,\$\$whence \$mu_n=1\$. For an odd integer \$n>0\$ we do this\$\$lim_xto 0,Biggl(x,left(fractexterfc_n(x)p_n(x)right)Biggr)=frac2^n-1n,binomn-1 fracn-12,left(frac2sqrtpiright)=lim_xto 0,Biggl(x,left(fracq_n(x)p_n(x)right)Biggr) ,,\$\$so also \$mu_n=1\$. This shows that \$q_n(x)=texterfc_n(x)\$ compared to all \$ninmathbbZ_geq0\$. Respectively, (*) and hold (#).

## Which function satisfies the differential equation?

A differential method is an equation that includes some unknown function y=f(x) and, on the other hand, several of its derivatives. A mixture of a differential equation is a nice solid function y = f(x) that satisfies my differential equation when f and its types are substituted into the equation.

#### Differential equationStatement

The first definition we need to consider is the fact of a differential equation. A differential formulation is an equation containing types: either ordinary derivatives or finite derivatives. There is a separate differential equation, which, probably, everyone is familiar with, this is Newton’s second law of motion. If an object of muscle mass (m) moves with a speed (a) and is acted upon by the command (F), then Newton’s second law tells us.

[beginequationF = ma labeleq:eq1 endequation]

To see that this is probably a differential equation, many of us had to rewrite it in a smaller size. First, remember that we can rotate and rewrite (a), an acceleration, in two ways.

[beginequationa implies fracdvdthspace0.25inmboxORhspace0.25in,,,,,,a = fracd^2udt^2 labeleq:eq2endequation]

Where (v) is the speed associated with the object (u), and in general the function of the object’s position here at any time (t). It is important to remember here that momentum (F) can also be a function of time, velocity and/or position.

So, we haveI mean with all this information, Newton’s second law can now be well written as a specific differential equation, either in terms of the actual velocity (v) or in terms of the position (u) that links to the object to be tracked.
