Question
In exercise problems 7 – 15, use the graph to find the limits (if it exists). If the limit does not exist, explain why?
`lim_(x -> x/2) tan x`

Solution
`lim_(x -> x/2) tan x`
y = f(x) = sec x
From the graph at x = `pi/2`, the curve does not intersect the line x = `pi/2`
At x = `pi/2`, he value of the function y = f(x) does not exist.
Hence `lim_(x -> x/2) tan x` does not exist.
