Question 1188589: Please help me solve this question.
A curve has the equation y=acosbx%2Bc , with a%3E0 . Given that the range of the curve is -4%3E=y%3E=2 and that the period of the curve is 180 , evaluate a, b and c . Hence sketch the graph of y for 0%3C=x%3C=360 .
P.S. for after the 180 and and for after the 0%3C=x%3C=360 there is a degree sign after the 180 , 0 and 360 .
