### Solving logistic regression equation for slope

I've calculated a logistic regression model involving two variables $X_1$ and $X_2$ and their interaction $X_1 \times X_2$ and obtained regression coefficients for each. The equation takes following ...

### Finding missing values with slopes

I am having difficulty with a math homework problem (grade 9). Given that $(m,18)$ is a point on the line $y=5x+58$, solve for $m$. I have been searching my notes and I cannot find anything like ...

### Linear clustering when plotting Pisano periods

Recently I saw a video on YouTube where the Fibonacci numbers were studied and around minute 4:20 appears a graph showing the period against the modulus. Something that caught my attention is that ...

### Best fit of deltas unequally spaced to reconstruct original curve

I have a collection of measurement deltas $m_1...m_n$ where each measurement consists of two points $(x_{n1},y_{n1})$ and $(x_{n2},y_{n2})$ the $x_{n1}$ and $x_{n2}$ represent where the measurement ...

### A term that describes the scenario when there is at one least trending data set for data sets over same time range

Given that I have 2 separate sets of plotted data points. Both data points run over the same time interval. Assume that at any given time interval, both datasets are either trending or one is trending ...

### In what sense not using a unit vector would "mess up" the directional derivative?

I've read dozens of questions and answers here regarding the usage of unit vectors when calculating directional derivative, and I get that it's only a convention and not mandatory. But the tendency to ...

### Finding x-axis-intercept of a parametric equation and slope

let $x = t^2$ and $y = t^3-3t$ now the equation for the slope is: $$\frac{dy}{dx} = \frac{3t^2-3}{2t} = 0$$ now at the point (0,0) is the first intercept with the x-axis with slope $\infty$ what is ...

### Doubt regarding finding the gradient of of a scalar field

I am new to vector calculus. I watched few you tube videos and came to the conclusion that directional derivative is something like slope with direction and its ...

### Find the Point/s on the Curve $y-x^3=0$ where the normal line have a slope of $\frac{-1}{3}$.

I am bit clueless on how to start the problem. The only idea I have is to use derivatives, yet I can't continue on. I have tried researching different problems connected to it as well, but the results ... 16 views

### negative slope of a triangle given only the sides

So my teacher gave me this graph and I needed to calculate the slope of the hypothenuse or f'(0.25). So 62/121 is positive and I can see that the slope is negative....

### How to prove this hypothesis regarding slopes and ellipses?

Let $a, b\in \mathbf{R}^+, \lambda >1$. $\Omega: \dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$, Point $M(\dfrac a{\lambda}, 0), A(-a,0),B(a, 0)$. Let line $l$ pass through $M$ and intersect with $\Omega$ at ...

### A question regarding the point-slope formula : does the formula really hold for any point of the straight line?

I can see only one way to derive the point slope formula, but this derivation also seems to bring a question. Let $D$ be the straight line of slope $m$ passing through point $P=(a,b)$. Let $Q=(x,y)$ ...
