For observed pairs , , the relationship between and can be defined generally as
where and . If we are unsure about the form of , our objective may be to estimate without making too many assumptions about its shape. In other words, we aim to “let the data speak for itself”.

# Property true for some integers and false for others: $-a^n$ = $(-a)^n$
I am currently working in my Discrete math class with elementary number theory and methods of proof. I have been given the problem $-a^n = (-a)^n$. According to the professor and the book this property is true for some integers and false for oth... | |

$\{a\}$
We are given: $U = \{a, b, c, d, e, f, g, h\}$ $A = \{a, g, h\}$ $B = \{b, g, h\}$ $C = \{b, c, d, e, f\}$ We need to determine $(A\cup B)\cap B'$ The union of sets $A$ and $B$ ($A\cup B$) is a set containing all distinct elements that are present in either $A$ or $B$. ... | |
## calculus
the area of a square with sides of length s is given by A=s^2. Find the rate of change of the area with respect to s when s=6 meters
## Answers (1)
• The rate of change of area with respect to s is just the derivative of A with respect to s:
then when s = 6
which is your final answer.

# Extended Hückel method
The extended Hückel method is a semiempirical quantum chemistry method, developed by Roald Hoffmann since 1963.[1] It is based on the Hückel method but, while the original Hückel method only considers pi orbitals, the extended method also includes the sigma orbitals.
The extended Hückel metho... | |
# Finding the common areas of two contourplots
I used ListContourPlot to specify an area for which the function value is less than a number. For example consider the following areas:

## Measuring Entropy and Entropy Changes
### Learning Objectives
• To gain an understanding of methods of measuring entropy and entropy change.

# Evaluating$\int {1\over1-\sin2x}dx$
$$\int {1\over1-\sin 2x}dx = \int {1\over \sin^2 x-2\sin x\cos x+\cos^2x}dx = \int {1\over (\sin x-\cos x)^2}dx$$
From here I get two different answers, depending on whether I factor out $\sin x$ or $\cos x$. Factoring out $\sin x$, this one is correct according to WolframAlpha:
