I dont see how z can be a constant and a variable. Anyway for finding a maximum you usually differentiate then set the derivative equal to zero and solve that to find maxs and mins. You can use the 2nd derivative to check if it a max or a min found.
I have an equation:
is a variable and is a constant which we can vary. This equation produces peaks in graphs. I'm asked to find the maximum value of at which peak will be produced. Which mathematic method would I use? Can I have hints please. Thanks in advance.
