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.
