How do you simplify the following?

#(1sin^2 x)/(sin x + 1)#

#(tan x)(1sin^2 x)#

#(1sin^2 x)/(sin x + 1)# 
#(tan x)(1sin^2 x)#

#(1sin^2 x)/(sin x + 1) = 1  sin x# when#x != (3pi)/2 + 2kpi# 
#(tan x)(1  sin^2 x) = 1/2 sin 2x# when#x != kpi#
Example 1.
Use the difference of squares identity:
Example 2.
Use the following:
as follows:

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
