Question 1207914
<pre>
{{{sec^"-1"(ln(x)) - ln(x + 1^""^""/(x^2 + 1)^0.05)}}}

There's nothing you can do with this that will be any simpler.
There is no way to simplify the log of a sum.  And it would
not be simpler to convert the inverse secant to an inverse
cosine.  

Why any teacher would give you an unsimplifiable expression 
to simplify is beyond me.
