expand (x^2ln(x))dy+(xy-1)dx

expand

(x^{2} ln (x)) d y + (x y - 1) d x

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

Solution steps

(x^{2} ln (x)) d y + (x y - 1) d x

Expand

d x (x y - 1) : x y d x - d x

= (x^{2} ln (x)) d y + x y d x - d x

Remove parentheses:

(a) = a

= x^{2} ln (x) d y + x y d x - d x

(\frac{3 i}{n} - 2)^{2}

(a + bi)^{5}

2 (3 e^{- x} x^{2} - e^{- x} x^{3})

cos (7 t) (5 + sinh (3 t) + e^{2 t})

\frac{d}{d t} ((h (t)) (2.8 t + 2.5))
