    graphing techniques for level curves

    Hi, I am having trouble graphing two level curves:

    1 = e^(-y) * tan (x)

    1/2 = cos(x) * cos(y)

    What is the best way to graph these? Should I be using calculus to find turning points and concavity?

    clarity?

    y=-\ln(\cot x)

    y=\arccos(\frac12\sec x)

    What is it exactly you are trying to do?
