I want to be able to plot the following equation into matlab and be able to graph it, but I'm not sure how to do it.

- x = - tan (y)

How would I go about this?

在 MATLAB Online 中打开

Perhaps —

x = @(y) tan(y)

x = function_handle with value:

@(y)tan(y)

figure

fplot(x, [-pi pi])

grid

xticks([-pi -pi/2 0 pi/2 pi])

set(gca, 'XTickLabel',{'$-\pi$', '$-\frac{\pi}{2}$' '$0$' '$\frac{\pi}{2}$' '$\pi$'}, 'TickLabelInterpreter','latex', 'FontSize',12)
