a) Find the exact solutions to the equation cosx-sin (2x) = 0 in the interval [0,2π). b) Graph one period of y=cosx and one period of y=sin(2x) on the same axes. Use the graph to demonstrate that these two graphs cross each other at the same values you found to be solutions in part "a." cos (-x) COSTCOSX c) Is the mathematical statement = 1- tanntanx an Equation or an Identity? If it is an identity, prove the statement is true. If it is not an Identity, find at least one value of "x" in the domain for which the statement is not true. a) Find the exact solutions to the equation cosx-sin (2x) = 0 in the interval [0,2π). b) Graph one period of y=cosx and one period of y=sin(2x) on the same axes.
