## Curve fitting with variable number of Gaussian curve

I have the data which appears like

And I decided to use three Gaussian curves to fit it.

(This code allows me to manipulate all three curves and put in best guesses for peak positions. Using these guesses, Mathematica wil…

## How would one go about plotting this parameterized curve using numerical resources (analitically it’s too hard)?

I’m working with the system of differential equations:
\begin{align*} \left\{ \begin{array} { l l } { (u’)^2 + (v’)^2 = 1 } \\ {u’v” – u”v’ = -v’ + u’ } \end{array} \right. \end{align*}
Where $u, v:I \to \mathbb{R}$. N…

## How do I plot a distance map in $R^2$ to a curve given in form $y=f(x)$?

As in the title, I’d like to display image using DensityPlot representing distance to a given curve, e.g., $y=x^2$.

I find it difficult to derive distance function to from a an arbitrary point to a curve (even for such simp…

## For a fixed-fixed cross currency swap, can I use a curve with two floating legs to discount the cash flows?

I’m doing a USD to INR fixed-to-fixed cross currency swap. The default curve has a fixed and a floating rate. However, the curve that I’m looking to use has floating rates on both legs. Would this curve be appropriate to use?…

## What should I change in my implementation to pass from a curve $y^2=x^3+1$ to $y^2=x^3+x$

I tried to change my implementation of pairing in curves $y^2 = x^3 + 1$ to use curves of the type $y^2 = x^3 + x$ but it didn’t work.

I thought the only thing I had to change in my code was the irreducible polynomial and …

## Where to find parameters for particular supersingular curve

In the PBC (Pairing Based Crypto) library, the curve parameters of the type A pairings are constructed on the curve $y = x^3 + x$ of embedding degree $2$.

I implemented a code for curves $y^2 = x^3 + 1$ of embedding degree \$…

## Anti Piketty Confusing Movement Along Demand Curve with Shift

In Anti-Piketty, the author’s claim that the statement

“If the supply of any good is insufficient and it’s price is too high, then demand for that good should decrease which should lead to a decline in its price”

is a misu…

## Why is polar curve of a glider dependent on flight load?

This is my first question here.
I’m just a glider in education phase and not yet a pilot, but because I’m also physicist, I’m interested in some details more than other people.

My question is simple:

I know what a polar cu…

## 3.P Do the rules assume a damage curve that can be abused? [on hold]

James Jacobs (Paizo Creative Director) obviously thinks so, but is he correct?

A response discussing getting the effects of Spirited Charge on every attack with a full attack. Pathfinder has clarified it only applies to the…

## When attempting a side or top curve spin in snooker do you need to adjust the aim of the shot?

I’m trying to get my head round this. I’m practicing positioning shots. If I want to hit the cue ball on the side, top, bottom etc do I need to aim slightly off for example hitting an angle to accommodate my strike.
