Can anyone explain how to do this? it's graphing tangent and cotangent

I don't see an equation with cotangent but I can graph .

The input of the tangent function is multiplied by .  Normally, the tangent function has asymptotes at .  Instead, each of these aymptotes will be divided by (when the input is multiplied, the known x values are divided).  That means the new function has asymptotes at .  The new function's period is 4.

Normally, the slope of the tangent function is 1 at 0, and whenever it crosses the x axis.  Your function is negative, so instead of drawing from negative infinity to infinity with a positive slope when it intersects 0, draw from positive infinity to negative infinity with a negative slope when it intersects 0.

I’d go with b hope it
