simplify cos(x+y)+(x^2)/6-(y^2)/6

simplify

cos (x + y) + \frac{x ^{2}}{6} - \frac{y ^{2}}{6}

cos (x + y) + \frac{x ^{2} - y ^{2}}{6}

Solution steps

cos (x + y) + \frac{x ^{2}}{6} - \frac{y ^{2}}{6}

Join

cos (x + y) + \frac{x ^{2}}{6} - \frac{y ^{2}}{6} : cos (x + y) + \frac{x ^{2} - y ^{2}}{6}

= cos (x + y) + \frac{x ^{2} - y ^{2}}{6}

2 x^{5} - 4 x^{4} - 9 x^{3} + 18 x^{2} + 4 x - 8

\frac{4 x ^{1}}{9}

16.1 x^{2} x + 50

\frac{16 x ^{2} + 4 x}{4 x}

(x - y)^{6} - 8 x^{3}
