# Spring Constant Formula
According to Hooke’s law, the force required to compress or extend a spring is directly proportional to the distance it is stretched.
## Spring Constant Formula
The formula of spring constant is given as:
Formula F=-kx SI unit N.m-1
Where,
• F is the restoring force of the spring direct... | |
# What is the 'sense' of a vector?
In my country we are taught of vectors as if they have three components, module (the length), direction (slope of the line that contains the vector), and 'sense' (sentido), which indicates the "way" or "sense" that the vector "goes". The vector $\vec{u}(5,6)$ has the same sense as $\... | |
## appleduardo Group Title what is the integral of e^(senx) 4cosx dx ? how can i solve it? one year ago one year ago
1. appleduardo
$\int\limits_{}^{}e ^{sen x} 4\cos x dx$
2. geerky42
sen? You mean sec?
3. satellite73
try $$u=\sin(x), du=\cos(x)dx$$ and you get it in one step

# Ask Uncle Colin: An Infinite Sum
Dear Uncle Colin
I've been asked to find $\sum_3^\infty \frac{1}{n^2-4}$. Obviously, I can split that into partial fractions, but then I get two series that diverge! What do I do?

# Theory data files
In the nnpdf++ project, FK tables (or grids) are used to provide the information required to compute perturbative QCD cross sections in a compact fashion. With the FK method a typical hadronic observable data point $$\mathcal{O}$$, is computed as,
$$\mathcal{O}_d= \sum_{\alpha,\beta}^{N_x}\sum_{i... | |
Question

# Are you kidding me?
Algebra Level 4
$\large \begin{cases} x^{2}-2xy+2y^{2}-20x+5y-4=0 \\ 3x+2y+1=0 \end{cases}$
Given that there exist two solution pairs $$(x_{1},y_{1})$$ and $$(x_{2},y_{2})$$ for the above system of equations, find $$x_{1}+y_{1}+x_{2}+y_{2}$$ correct to three decimal places.

# How do you graph of y=-(1/5)^x and state the domain and range?
Feb 4, 2017
Domain $\left(- \infty , \infty\right)$. Range : $\left(- \infty , 0\right)$. See graph and explanation.
#### Explanation:
$y = - {\left(\frac{1}{5}\right)}^{x} < 0 \mathmr{and} \to 0$, as $x \to \infty$.
y-intercept ( x = 0 ) : $- 1$

# Genetic Drift
[…] in a finite-sized population the proportion of alleles fluctuates due to stochastic sampling errors, so even in the absence of any selective pressure, the genes will eventually become fixated at one particular allele. – Thierens 19981
