## Study Notes

## Algebra

Algebra is one of the fundamental branches of mathematics that deal with variables, equations, and expressions using symbols instead of numbers. It provides a framework to solve problems involving unknowns by manipulating their relationships symbolically.

### Linear Equations

Linear equations are a special type of equation where all terms have degree one. They can be represented in the form `ax + b = 0`

, where `a`

and `b`

are constants and `x`

represents the variable. Solving linear equations involves finding values of the variable that make the left side equal to zero. This can often be done through substitution, elimination, or graphing techniques.

### Quadratic Equations

Quadratic equations are a more complex type of nonlinear equation that involve squared variables such as `x^2`

. They are expressed in the general form `ax^2+bx+c=0`

, where `a`

, `b`

, and `c`

represent coefficients and `x`

represents the solution. To find the roots of quadratic equations, we use quadratic formula which is `(-b±√(b²-4ac))/(2a)`

, where `b²-4ac`

is called discriminant.

## Geometry

Geometry is another essential branch of math that focuses on shapes, sizes, positions, and dimensions. In geometry, mathematical concepts are applied to physical phenomena such as space, lengths, angles, areas, and volumes.

### Triangles

A triangle is a polygon with three edges and three vertices. It has several important properties like congruence, similarity, and trigonometric ratios. There are different types of triangles based on their sides and angles, including equilateral, isosceles, scalene, acute, right, obtuse, and oblique.

### Circles

Circle is a geometric shape with all points at an equal distance from its center. Its area can be calculated using the formula `πr²`

where `r`

is the radius of the circle. Perimeter of a circle can be found by multiplying circumference constant `C`

with diameter `d`

- i.e., `Cd`

. The angle subtended at the center of a circle is half the angle subtended at any point on the circle's perimeter..

## Calculus

Calculus is a major area of advanced mathematics dealing with rates of change and accumulation of quantities. Calculus consists of two main branches: differential calculus, which deals with the study of functions and their derivatives; and integral calculus, which studies the anti-derivatives of real-valued functions.

### Differentiation

Differentiation refers to the process of finding the derivative of a function. Derivatives measure how much a function changes when the input changes by a small amount. If `f(x)`

is a differentiable function, then the derivative of `f`

evaluated at `x`

is denoted as `f'(x)`

or `df/dx`

.

### Integration

Integral calculus is concerned with finding the antiderivative of a given function. It is used to calculate definite integrals, which provide information about the area under a curve between specified limits. A Riemann sum is generally considered to be converging to the definite integral if the average height of rectangles approximates the exact value within an error tolerance.

## Statistics

Statistics is the branch of mathematics that deals with data collection, organization, analysis, interpretation, and presentation of results. It involves methods for gathering and analyzing large amounts of data, applying probability theory, and making conclusions and predictions based on this data.

### Probability Distributions

Probability distributions describe the likely outcomes of random events. Some common distribution families include uniform, normal (or Gaussian), binomial, Poisson, exponential, and gamma. These distributions help us understand patterns in the occurrence of certain events.

### Statistical Inference

Statistical inference uses statistical methods to draw reliable conclusions from sample data about a population. It includes hypothesis testing, estimation, confidence intervals, and goodness-of-fit tests. Hypothesis testing helps researchers determine whether there is sufficient evidence to reject or accept a null hypothesis based on sample data.
