Homework Statement
Find limit for x tending to infinity of: (e^(x^-2)-1)/(2arctan(x^2) - pi)
Homework Equations
arctanx +arccotx=pi/2
arctanx=arccot(1/x)
The Attempt at a Solution
P.S I haven't written limit before each step, and hope you can get how I arrived at the first step.I just took 2 common from the denominator and used simple inverse trig.
However,the answer is -1/2
Where am I going wrong?
