# The Fibonacci Sequence

This video introduces the Fibonacci sequence and provides several examples of where the Fibonacci sequence appear in nature.

# Ex: Find Continuous Interest Rate Given f(t)=ab^t

This video explains how to write an exponential function in the form f(t)=ab^t in the form y = ae^(kt) to determine a continuous rate.

# Ex: Find Annual Interest Rate Given f(t)=ae^(kt)

This video explains how to write an exponential function in the form f(t)=ae^(kt) in the form y = ab^t to determine an annual rate.

# Ex: TI84 TVM Solver – Present Value Value with Compounded Interest

This video explains how to use the TVM Solver on the TI84 to determine the present value needed to obtain an account balance that pays compounded interest.

# Ex: TI84 TVM Solver – Future Value with Compounded Interest

This video explains how to use the TVM Solver on the TI84 to determine the future value of an account that pays compounded interest.

# Ex: Exponential Function Applications – Increasing Investment Value (Change of Base Used)

This video explains how to write an exponential function to model a increasing investment account balance. An exponential equation is solved using the change of base formula.
