expand (2x-y+1)dx+(4x-2y+3)dy

expand

(2 x - y + 1) d x + (4 x - 2 y + 3) d y

2 x d x - y d x + d x + 4 x d y - 2 y d y + 3 d y

Solution steps

(2 x - y + 1) d x + (4 x - 2 y + 3) d y

Expand

d x (2 x - y + 1) : 2 x d x - y d x + d x

= 2 x d x - y d x + d x + (4 x - 2 y + 3) d y

Expand

d y (4 x - 2 y + 3) : 4 x d y - 2 y d y + 3 d y

= 2 x d x - y d x + d x + 4 x d y - 2 y d y + 3 d y

(s + 1.47) (\frac{0.5}{s + 1.47} + 1.7)

cos (2 θ) + tan (θ) (sin (2 θ) + tan (θ))

\frac{5 ( 2 x - 1 ) ( 2 x + 1 )}{( x - 5 ) ( x + 5 )}

x^{4} (x^{5} - 10)^{12} d x

7 (\frac{2}{13} x + \frac{3}{13} y)^{2}
