Find an equation toe the graph shown Type the equation of the given graph in the form y = A sin (omega x) y = (Simplify your answer type an exact answer in terms of pi. Use integers or fractions for any numbers in the expression.)

Solution

Since garph has amlitude =5

when x=0 , y=-5

when x=3pi/2, y=5

when x=3pi/4, y=0

so, the graph fit the equation y=Acos(wx)= -5cos(2x/3)
