What is the period of the sinusoid given by y=-3cos(2pi/5 x)?
y=a cos (bx+c) +d
a=-3; b=2pi/5; c=0; and d=0
Answer: The period of the sinusoid given by y=-3cos(2pi/5 x) is 5.
From the answer and question examples above, hopefully, they could simply guide the student resolve the question they had been looking for and observe of all declared in the answer above.
