List all solutions to 2sin(x)cos(x) + cos(x) = 0. Give your answers in degrees or radians. Homework Help ✎
Factor out the cos(x) from the equation.
Use the Zero Product Property to solve for x.
Find all the solutions to these statements either using a unit circle or by graphing the functions on a graphing calculator. Do not just take this inverse on your calculator, it will only give you one possible solution. Remember, each of the 4 solutions repeats every 2πn radians.
