to match.pd.
Move Optimize pow(x,y)*pow(z,y) as pow(x*z,y)to match.pd.
Move Optimize tan(x)*cos(x) as sin(x) to match.pd.
Move Optimize x*pow(x,c) as pow(x,c+1) to match.pd.
Move Optimize pow(x,c)*x as pow(x,c+1) to match.pd.
Move Optimize sin(x)/cos(x) as tan(x) to match.pd.
Move Optimize cos(x)/sin(x) as 1.0/tan(x) to match.pd.
Move Optimize sin(x)/tan(x) as cos(x) to match.pd.
Move Optimize tan(x)/sin(x) as 1.0/cos(x) to match.pd.
Move Optimize pow(x,c)/x as pow(x,c-1) to match.pd.
Move Optimize x/pow(y,z) into x*pow(y,-z) to match.pd.
