What is an Exponential Function? Exponential function is one of type of function. It is non algebraic (transcendental) function which cannot operate with addition, subtraction, multiplication, division of difference variables raised to some non-negative integer power. Exponential function is not only in mathematics, but also in physics as the application. Exponential Function Equation The general
Logarithm is one of basic mathematics concept. Logarithm counts repeated same number in multiplication form. Operating logarithm means determine how many repeated numbers (b) to get the result (x). Logarithm is used to many sectors in life. Some of them are calculate the magnitude of earthquake using Richer Scale, loudness of sound in decibels (dB),
Definition of Continuous Function Function describe as a relation of each value from the first set that is associated exactly one value from another set. Function has many types in mathematics. One of them is continuous function. Continuous function is one of topics in calculus. Continue means unbroken. Continuous function is a function that has
Multiply the tops, then multiply the bottoms. How to multiply fractions There are 3 simple steps to multiply fractions Multiply the the numerators (top numbers). Multiply the denominators (bottom numbers). Simplify the fraction if needed. Example Step 1 Multiply the the numerators Step 2 Multiply the denominators Step 3 Simplify the fraction Mulltiplying Fractions and Whole Numbers
FOIL Method is a handy way to remember how to multiply 2 binomials. Definition FOIL stands for “First, Outer, Inner, Last“ F O I L First Outer Inner Last It is the sum of: multiplying the First terms, multiplying the Outer terms, multiplying the Inner terms, and multiplying the Last terms. Examples (a+b)(c+d) = ac + ad +

Definitions a Combination is when the order doesn’t matter. a Permutation is When the order does matter. In other words: A Permutation is an ordered Combination. Permutations There are 2 types of permutation: Permutation with Repetition: such as the lock. It could be “444”. Permutation without Repetition: for example the first three people in a
Taylor series is one of topic in numerical method. It describes the sum of infinite terms of any functions. If there are more and more terms, it will give the high accuracy. It was introduced by English mathematicians, Brook Taylor. One of Taylor series application is scientific calculator operation. Sometimes when we need to determine
Example Solve x + y + z = 6 2y + 5z = −4 2x + 5y − z = 27 Change into matrix form AX = B where A is the 3×3 matrix of x, y, z coefficients X is x, y, z B is 27, 6, −4 Then find the value of x, y, z X =
SAS (Side, Angle, Side) is when we know 2 sides and the angle between them. How to solve an SAS triangle ? use the Law of Cosines to calculate the unknown side, use the Law of Sines to find the smaller of the other two angles, use the three angles add to 180° to find
