D(Sin(x)^2, x) gives result as 2cos(x)^2

[Former user]

With your latest library D(Sin(x)^2, x) Expected output : 2Sin(x)Cos(x) Output : 2cos(x)^2

I cannot reproduce the issue? Can you a show a code snippet, how you tested it?

See this JUnit test: https://bitbucket.org/axelclk/symjaunittests/commits/bc2580ff06994c40e350305868cc7dd01c0d531c

I used SymjaDroid with your latest jar

Don't know why, but in the Android emulator environment the java.util.AbstractList#equals() gets true comparing Sin(x) and Cos(x) ?

With this change there's a workaround implemented in HMArrayList#equals() method: https://bitbucket.org/axelclk/symja_android_library/commits/06ae1c0d6aa367164a355526a7d5153c32e1953c
