What are the steps to solving this limit?

lim(x>0) = -5

Step-by-step explanation:

first: sin(x-π/2)= -cosx

so the equation will be :

lim(x>0) = [-6cos(ax)-1}/cosx

solve :

lim(x>0) =  [-(6cos(a(0))-1}/cos(0)

cos0=1

lim(x>0)=(-(6(1)-1)/1

lim(x>0)=-6+1/1

lim(x>0)=-5

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
