# Determine the Relative Frequency from a Frequency Table

This video explains how to determine the relative frequency from a frequency table.

# Ex: Find the Intervals Incr/Decr and Relative Extrema Using the First Derivative

This video explains how to use the first derivative to determine intervals for which a function is increasing or decreasing.  The  relative (local) extrema are also found.

# Ex: Find the Intervals Incr/Decr and Relative Extrema (Quad Formula Used)

This video explains how to use the first derivative to determine intervals for which a degree 5 polynomial is increasing or decreasing.  The location of relative (local) extrema is also found.

# Introduction to Differentials

This video defines differentials, finds differentials of functions, uses differential to estimate a function value, and find propagated and relative error.

# Ex: Percent Applications – Changing Bases of Relative Change

This video explains how to find various relative change or percent change with different bases.

# Ex: Change, Absolute Change, and Relative Change
