“Your Turn” from “Example 2” on page 270 of the textbook
An algebraic solution is shown.
Since the sine function is positive in quadrants 1 and 2, a second possible value of x can be calculated.
Because the b value is the period is 8. Thus, the general solution for the equation is x ≈ 0.432 + 8n, n ∈ I, x ∈ R and x ≈ 3.567 + 8n, n ∈ I, x ∈ R.
A graphical solution is shown.
