Exponential and Logarithm Functions

Exponential and logarithm functions are a very important part of mathematics in both theory and practice. They can be used to model real-world situations, exponential functions are used to model population, compute investments, carbon date artifacts, radioactive decay, bacterial growth, cooling of objects and so on. On the other hand, logarithm functions are used in calculating interest rate, defining and expressing the unit of the power of a sound wave – decibel measures, to calculate exposure in photography, earthquakes (Richter scale), the brightness of stars, pH balance, acidity and alkalinity, and many other real life examples.

In MatDeck, exponential and logarithm functions cover all aspects using several functions that can assist and aid you to calculate complex exponential and logarithm functions lightning fast.

These MatDeck functions are:

exp – Exponential function that uses e (Euler’s number) base
exp2 – Exponential function with number two base
expm1 – Exponential function with e (Euler’s number) base subtract one
ldexp – Multiplies a floating point argument by the number 2 raised to the exp power
frexp – Decomposes floating point argument into a normalized fraction and an integral power of two
ln – Natural logarithm (base e Euler’s number) of argument
logb – Extracts exponent from the number
log – Calculates logarithm (base 10) of argument
log2 – Calculates logarithm (base 2) of argument
logax – Calculates logarithm base a of argument x
log1p – Calculates natural logarithm (base e) of 1 + argument
pow – Calculates x to the power of n (exponential functions which base isn’t Euler’s number)

MatDeck’s 2D and 3D graphs can plot exponential and logarithm functions in real or complex planes, use exponential and logarithm regressions to model and predict different real-world situations, export and save calculations made with these functions, calculate their derivatives (numerical or symbolical) and integrals (numerical),etc.
