Certainly! Here are
a few additional important mathematical formulas:
- Quadratic
Formula: For a quadratic equation ax² + bx + c = 0, the solutions for x
can be found using the formula: x = (-b ± √(b² - 4ac)) / 2a
- Distance
Formula: The distance between two points (x₁, y₁) and (x₂, y₂) in a
coordinate plane can be calculated using the formula: d = √((x₂ - x₁)² +
(y₂ - y₁)²)
- Slope-Intercept
Form: The equation of a line in slope-intercept form is y = mx + b, where
m is the slope of the line and b is the y-intercept.
- Mean (Average):
The mean of a set of numbers is calculated by adding up all the numbers
and dividing by the total count.
- Median: The
median is the middle value in a sorted set of numbers. If there is an even
number of values, the median is the average of the two middle values.
- Mode: The mode
is the value that appears most frequently in a set of numbers.
- Probability:
Probability of an event occurring can be calculated using the formula:
Probability = (Number of favorable outcomes) / (Total number of possible
outcomes)
- Surface Area of
a Sphere: The surface area of a sphere with radius r is given by the
formula: SA = 4πr²
- Volume of a
Sphere: The volume of a sphere with radius r is given by the formula: V =
(4/3)πr³
- Area of a
Parallelogram: The area of a parallelogram is given by the formula: A =
base x height
Remember that these additional
formulas cover a range of topics and may be introduced in higher grade levels
or specific mathematical topics. It's essential to refer to the relevant
chapters and textbooks to understand and apply these formulas accurately.

Exponents:
- Product Rule:
am * an = am+n
- Quotient Rule:
am / an = am-n
- Power Rule:
(am)n = amn
- Distance,
Speed, and Time Relationship: The relationship between distance (d), speed
(s), and time (t) can be represented by the formula: d = s * t
- Probability of
Independent Events: For two independent events A and B, the probability of
both events occurring is given by: P(A and B) = P(A) * P(B)
- Pythagorean
Theorem (in 3D): In a right-angled triangle in three-dimensional space,
the square of the hypotenuse is equal to the sum of the squares of the
other two sides.
- Arithmetic
Progression (AP): The nth term of an arithmetic progression can be
calculated using the formula: an = a1 + (n - 1) * d, where a1 is the first
term and d is the common difference.
- Geometric
Progression (GP): The nth term of a geometric progression can be
calculated using the formula: an = a1 * r^(n - 1), where a1 is the first
term and r is the common ratio.
