A cone is a solid figure formed when the other two sides of a right triangle are rotated 360 degrees around the line of the triangle's right-angle side.
Factoring is all about turning a polynomial into a product of several polynomials. It's the reverse of polynomial multiplication, and the main goal is to simplify things.
Approximate equality is a symbol used in math to represent numbers that are close in value. It's written as '≈' and read as 'approximately equal to'.
Trigonometric functions are a type of function in math that deal with angles. They connect the measurement of an angle with the ratios of the sides of a right triangle containing that angle, and they are a basic tool for studying triangles and periodic phenomena.
The imperial system is the traditional system of measurements in the UK, with main units like feet, pounds, and gallons. Conversions are complicated, and it's mostly been replaced by the metric system now, but places like the US still use it a lot.
In real life, 'images' are mainly abstracted in math as 2D functions, pixel matrices, or geometric trajectories.
Decimal calculations are mainly taught from third to fifth grade. The depth of the content and the types of operations vary across different grades.
A line segment is the part between two points on a straight line; it has endpoints at both ends and a fixed length.
Decimal point, a math symbol, written as '.', used in decimal numbers to separate the integer part from the fractional part.
A linear equation, also called a first-degree equation, refers to an equation where all the unknowns are to the first power.
