Exponential function: An exponential function is a mathematical function where the independent variable appears in the exponent. It can be written in the form f(x) = a * e^(kx), where "a" and "k" are constants.
Initial value: In calculus, initial value refers to the value of a function or equation at a specific starting point or initial condition. It helps determine the behavior and characteristics of the function over time.
Natural logarithm:The natural logarithm, denoted as ln(x), is the inverse operation of raising Euler's number (e) to a power. It gives us the exponent needed to obtain a certain value when e is raised to that power.
