To understand the expression “arcsin(u/a) + c,” let’s break it down into its components:

1. “arcsin(u/a)”: This represents the inverse sine function. It is denoted as “arcsin” or “sin^(-1)” and is used to find the angle whose sine value is equal to a given ratio. In this case, we have “u/a,” where “u” and “a” are variables or numbers. The inverse sine function will determine the angle whose sine value is “u/a.”

2. “+ c”: The “+ c” at the end of the expression represents a constant “c.” This is added to the result obtained from the inverse sine function. It helps in accounting for any translations or shifts in the graph of the function.

So, when you add “arcsin(u/a)” and “c” together, you are effectively finding the inverse sine value of “u/a” and then adding the constant “c” to the result of that function.

For example, if you are given the equation y = arcsin(x/a) + c and asked to graph it, you would start by plotting the graph of y = arcsin(x/a) (the inverse sine function), and then shift the entire graph upward or downward by a distance of “c.”

It’s important to note that the inverse sine function has a restricted domain of [-1, 1], as the sine ratio can only take values in that range. So, when working with “arcsin(u/a) + c,” make sure that the value of “u/a” falls within the domain of the inverse sine function.
