Part a
Using your Graphing Calculator (GDC), solve the equation \(\cos(2x)=0.15\) for \(0^\circ \leq x \leq 360^\circ\). Clearly show how you use the solver function to determine the approximate values of \(x\). Ensure you find all solutions within the domain and remember to divide the solution for \(2x\) by 2 to obtain \(x\). State your answers to […]
