expand cosh((3t-6)U(t-2)3t)

expand

cosh ((3 t - 6) U (t - 2) 3 t)

cosh (9 t^{3} U - 36 t^{2} U + 36 t U)

Solution steps

cosh ((3 t - 6) U (t - 2) \cdot 3 t)

Expand

(3 t - 6) U (t - 2) \cdot 3 t : 9 t^{3} U - 36 t^{2} U + 36 t U

= cosh (9 t^{3} U - 36 t^{2} U + 36 t U)

\frac{75 ( 4 ^{24} + 4 ^{23} \cdot 72 )}{4 ^{25}}

(a + b + c) (e + f + g) (h + i + j)

\frac{6 - x}{x ( x - 3 )}

\frac{3 x ( - 2 x - y + 3 ) ^{2}}{2}

\frac{2 ( 60 x ^{4} - 53 x ^{2} + 12 )}{x ( 3 x ^{2} + 4 ) ( 20 x ^{2} + 3 )}
