Bugs inIntegrate[] #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
Calling the functions: "Integrate[Sin[x]^3,x]", "Integrate[Cos[2x]^3,x]".

What is the expected output? What do you see instead?
The functions don't work.

What version of the product are you using? On what operating system?

Please provide any additional information below.
I see the rules of Integrate[] function about power of Sin, Cos. But they don't 
work.

There was a bug in PatternMatcher#equivalent() method, which deleted some 
Integrate[] rules.
