expand (t-1)cosh(2t)

expand

(t - 1) cosh (2 t)

t cosh (2 t) - cosh (2 t)

Solution steps

(t - 1) cosh (2 t)

= cosh (2 t) (t - 1)

Apply the distributive law:

a (b - c) = ab - a c

cosh (2 t) (t - 1) = cosh (2 t) t - cosh (2 t) \cdot 1

= cosh (2 t) t - cosh (2 t) \cdot 1

Simplify

cosh (2 t) t - cosh (2 t) \cdot 1 : t cosh (2 t) - cosh (2 t)

= t cosh (2 t) - cosh (2 t)

\frac{4 x ^{2} - y ^{2}}{2}

(x - 5) (x - 7)

(2 x^{2} y + 2 y + 5) d x + (2 x^{3} + 2 x) d y

x y d x + (x^{2} + y^{2}) d y

lo g_{10} (x^{9} y^{- 10})
