The ratio of the ions in an ionic compound depends on the charges of the ions. The amount of positive charge must balance the amount of negative charge. For each compound, both the total positive charge and the total negative charge will equal the LCM found in part B. Determine the number of positive ions and the number of negative ions for each ionic compound in the table. Use the ionic charges of each element you found in part A. The number of each ion times the charge on the ion should equal the LCM determined for each cell in part B. [# of ions of an element] × [ion charge] = least common multiple (LCM) Drag each element's chemical symbol to the table to show how many ions are needed to balance the charges. Each symbol will be used more than once. The first row is already completed for you.

A multiple is the result of multiplying a number by an integer. The least common multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers. To find the least common multiple you need to be able to identify the factors of the numbers you are working with.

Step-by-step explanation:

what group of numbers are you talking about?

We will begin with the graph of the tangent function, plotting points as we did for the sine and cosine functions. Recall that

The period of the tangent function is π because the graph repeats itself on intervals of kπ where k is a constant. If we graph the tangent function on

, we can see the behavior of the graph on one complete cycle. If we look at any larger interval, we will see that the characteristics of the graph repeat.

We can determine whether tangent is an odd or even function by using the definition of tangent.
