# What is the limit of lim (tan(x-(p/2))/(x-(p/2)-cos(x)) when x approach to (p/2) ?tan(x-(p/2)) not tan (x+(p/2))Please I need detailed answer.

I'm so sorry I mistyped again the syntax of limit
it's lim (tan(x-(p/2))/(x-(p/2)+cos(x))
not lim (tan(x-(p/2))/(x-(p/2)-cos(x))
the sign of cos will make difference you will get +ifini -infini but I can't prove that i just GeoGebra to draw it.
so can you please explain me how can i calculate
lim (tan(x-(p/2))/(x-(p/2)+cos(x)) ?
I'm sorry again

i said the lim_(x -gt pi/2) (tan(x-pi/2))/((x-pi/2)-cos(x))`
not lim_(x -gt pi/2) (tan(x-pi/2)/(x-pi/2)-cos(x))`
