## How to solve this inequality?...

solve(a/(x+1)>1,x)

When I type this command and run it,It returns nothing but this warning

"Warning, solutions may have been lost"

How can I get the correct solution using Maple 18

## Distinguish between list and Array...

a:=[1,2,3]:

b:=[1,2,3]:

evalb(a=b)    #The result is true

c:=Array([1,2,3]):

d:=Array([1,2,3]):

evalb(c=d)    #The result is false

This is Why?

Maple

When I input

cos(k*Pi) assuming k::odd

The result is -1

but

(-1)^k assuming k::odd

The result is (-1)^k

Why doesn't the second expression work?

## wrong taylor expansion result...

Maple

taylor(1/(1+z^2), z = 1, 4)

The result is

1/2-(1/2)*z-1+(1/4)*(z-1)^2+O((z-1)^4)

but in fact the result is

1/2-(1/2)*(z-1)+(1/4)*(z-1)^2+O((z-1)^4)

my Maple is Maple 16,How to solve this problem?
