Find the coordinates of the turning point of y=e^(2x)*cos(x)?

  • Think about which process we need to determine the turning point? - Differentiation 

  • Think about the form of the given function. - Product of two functions, so use Product Rule for Differentiation 

-Process the derivative

  • How do we find the turning point from the derivative? Set it equal to zero and solve

  • Solve for the x-coordinate.

  • Don't forget to find the y-cordinate.
