Question

For the function y= -3+4 cos(5pi/6(x+4)) , what is the maximum value?

Answer 1

The maximum value of the function  y= -3+4 cos(5pi/6(x+4)) can be determined by differentiating the equation then make the derived function equal to zero. In this case, the function becomes 4 sin (5pi/6(x+4)) * (5pi/6) or equal to 10pi/3 sin (5pi/6(x+4)) = 0. sin -1 of 0 is equal to zero. hence, 5pi/6(x+4) should be zero. x is equal to -4. substituting -4 in the original equation,y= -3+4 cos(5pi/6(-4+4)) is equal to 1. The maximum value is 1. 

Answer 2

For the problem presented, the maximum value for the function y= -3+4 cos ( 5pi/6 (x+4) ) is 1. I am hoping that this answer has satisfied your query about this specific question, thank you and have a nice day.
