How to use it?
- Factor polynomial:
- z^3-z^2-2*z/5+8/125
- z^3-2*z^2+z-2
- y^8-x^8
- -y^3+y^2-1
- Least common denominator:
- (z-2)/(6*z+(z-2)*(z-2))+(6/(z*z*z-8))
- sin(x)/(2*(1-cos(x))*sqrt(1+cos(x)))-(sqrt(2)-sqrt(1+cos(x)))*sin(x)/(1-cos(x))^2
- pi/(sqrt(1-x^2)*(exp(x)-log(x)))+pi*(1/x-exp(x))*asin(x)/(exp(x)-log(x))^2
- (z^5-5*z^3+10*z-10/z+5/z^3-1/z^5)*(z^3-3*z+3/z-1/z^3)
- Factor squared:
- y^4-3*y^2-2
- y^4-3*y^2-12
- x^2+3*x-4
- -y^4-9*y^2+7
- How do you in partial fractions?:
- z/(2*z-4)-(z^2+4)/(2*z^2-8)-z/(z^2+2*z)
- y/(y+3)+y/3+2/y
- x/(x^3-1)
- 1/(cos(x)^2)
