What is θ in math?

θ theta. Commonly used as a variable to indicate an. angle.

What does ⋅ mean?

The ⋅ is the same as the × multiplication sign, but it is often used in mathematical notations to prevent possible confusion with the letter ‘x’. e.g. y × x is often written as y ⋅ x. This sign is used to represent equivalence.

What is the equation ofa vertical line?

The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .

What kind of line is equal symbol?

The equal sign, equals sign, or “=” is a mathematical symbol used to indicate equality. It looks like two parallel horizontal lines. The equals sign is placed between the things stated to be exactly equal or the same.

Is Pi a real numbers?

Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666…). (To only 18 decimal places, pi is 3.141592653589793238.)

When do vertical lines go up or down?

Vertical lines go up/down, but they never go left or right. This means the change in Y = 1, while the change in X = 0. 1/0 = undefined. Hope this helps. Comment on Kim Seidel’s post “Remember, the slope of a line is “change in Y / ch…”

What is the slope of a vertical line?

The slope is never the X point. The slope of a line is change in Y / change in X. The slope of a horizontal line = 0, not undefined. The slope of a vertical line = undefined.

What does the denominator mean on a horizontal line?

The denominator tells you the change in X — how fast the X coordinate is changing (how fast the line is moving left/right). Horizontal lines do not go up/down. They just move left to right. This means the change in Y = 0, while the change in X = 1. 0/1 = 0 as a slope.
