How to draw this implicit function?
The equation x^2 - y^2 == Tan[y^x] is equivalent to the series of the equations ArcTan[x^2 - y^2] == y^x + k*Pi, where k∈ Integers. Therefore,
ContourPlot[Evaluate[Table[ArcTan[x^2 - y^2] == y^x + k* …

through
ContourPlot[1/2 - Abs[y] ==Sqrt[(1/2 - Abs[y])^2+(y-Sin[x])^2],

Problem with Plot
The command
Plot[Log[27, Sin[2*x] - 1/3*Cos[x]] - 1/3*Log[3, -Cos[x]], {x, -Pi, Pi}]
performs
However, this result contradicts both calculus over the reals, where $\log_3(-\cos x)$ is not define …

Plotting an integral
NIntegrate
instead of Integrate does the job:
LogLogPlot[1.1183*3.086*10^-12 (c^(1/2))*2.598*10^-3 NIntegrate[ x^(1/2) Exp[-10.7*

ContourPlot fails with composite condition?
How about
ContourPlot[Boole[x^2 + y^2 == 1 || x^2 + y^2 == 2], {x, -2, 2}, {y, -2, 2}]
? Please, play with color on your own.

Plot and mention extremum with corresponding points of extrema
Here are plots:
ComplexPlot[Log[Abs[h[v]]], {v, 0 + 0*I, 10 - 10*I}]
ComplexPlot3D[Log[Abs[h[v]]], {v, 0 + 0*I, 10 - 10*I},PlotPoints -> 50]
It is difficult with the extrema since ComplexExpand[h[ …

ContourPlot is not accurately capturing contour lines
There is a workaround, at least for the case under consideration.
ListPlot[{x, y} /.FindInstance[(x^2/4 + y^2 - 1)^2 == 0 && RealAbs[x] <= 2 &&
RealAbs[y] <= 2, {x, y}, Reals, 25000]]
