Question

Solve each equation separately to get the full solution set, choosing only solutions on the interval [0,2π).

Answer 1

To solve equations within the interval [0,2π) radians, identify knowns, select the appropriate equation or set of equations, substitute known values with correct units, and check if the obtained solution is reasonable.

Step-by-step explanation:

Solving Equations on the Interval [0,2π)

When solving equations, particularly in trigonometry, students are often asked to find solutions within a specific interval, such as [0,2π) for angles measured in radians. To do this, one must:

• Identify the known values and what can be inferred from the problem statement.
• Use appropriate equations that can solve for the unknown. In cases where there are multiple unknowns, simultaneous equations might be required.
• Substitute the known values into the equation and solve, ensuring that units are consistent—using radians for angular measurements.
• Reflect on the solution to check if it is reasonable.

Often, the process involves many algebraic steps and may require the application of specific rules, like the loop rule in circuit analysis. Throughout, careful consideration of physical principles and checking of algebraic manipulations is critical.
