Question 730757
((1-sin(x)*cos(x))sin(x))/(sin(x)-cos(x)))*((sin^2(x)-cos^2(x))/(sin^3(x)+cos^3(x)
((1-sin*cos)*sin)/(sin-cos))*((sin^2-cos^2)/(sin^3+cos^3))
use sum of cubes and difference of squares
((1-sin*cos)*sin/(sin-cos))*((sin+cos)(sin-cos)/(sin+cos)(sin^2-sincos+cos^2))
Identity:cos^2+sin^2=1
((1-sin*cos)*sin/(sin-cos))*((sin+cos)(sin-cos)/(sin+cos)(1-sincos))
((1-sin*cos)*sin/{{{cross("sin-cos")}}}))*(({{{cross("sin-cos")}}}{{{cross("sin+cos")}}}/{{{cross("sin+cos")}}}(1-sincos)
((1-sin*cos)*sin)/(1-sin*cos)=sin
