1) (x^3) ln(x) + x^3 (1/x)= x^3 * ln(x) + x^2
2) e^x cos(x) - e^x sin(x)= e^x * (cos(x) - sin(x))
3) x sin(x) + 1 sin(x)= x * sin(x) + sin(x)
4) 2x - 6 ln(x) - 6= 2x - 6 ln(x) - 6
1) (x^3) ln(x) + x^3 (1/x)
= x^3 * ln(x) + x^2
2) e^x cos(x) - e^x sin(x)
= e^x * (cos(x) - sin(x))
3) x sin(x) + 1 sin(x)
= x * sin(x) + sin(x)
4) 2x - 6 ln(x) - 6
= 2x - 6 ln(x) - 6
