Question 1032800: Using complete sentences, explain how to find the maximum value for each function and determine which function has the largest maximum y value.
Function f(x)=2 cos(x) and function g(x)= 3 times sin (x+ pi)

The maximum value for any cosine or sine function is 1; therefore, the coefficient of each function determines which one has the largest maximum y value.
2 cos(x) has a maximum value for x=0 or 2 pi, and it is 2.
3 sin(x+pi) has a maximum value for x=3pi/2 or -pi/2, and it is 3. The function that has a value of (0,2) is the cosine; the other is the sine.
