Final answer:
The question asks for the value of 'm' when the maximum of the function y=cos x/sin x is at x = π/4, but without additional context, 'm' cannot be determined.
Step-by-step explanation:
The question asks if the maximum value of the function y=cos x/sin x is at x = π/4, what is the value of m. In the context provided, no direct reference to the variable m is made within the question. Therefore, it's impossible to determine the value of m based solely on the information provided without additional context.
Analyzing the function y=cos x/sin x, which simplifies to cot x, we know that its maximum value at x = π/4 would be 1 since cos (π/4)/sin (π/4) = √2/2 /√2/2 = 1. However, this piece of information doesn't give us enough to solve for m. More context about how m relates to the problem would be needed.
