expand y(x^2+y^2-1)dx+x(x^2+y^2+1)

expand

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

y x^{2} d x + y^{3} d x - y d x + x^{3} + y^{2} x + x

Solution steps

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

Expand

y d x (x^{2} + y^{2} - 1) : y x^{2} d x + y^{3} d x - y d x

= y x^{2} d x + y^{3} d x - y d x + x (x^{2} + y^{2} + 1)

Expand

x (x^{2} + y^{2} + 1) : x^{3} + y^{2} x + x

= y x^{2} d x + y^{3} d x - y d x + x^{3} + y^{2} x + x

(e^{i θ} - e^{- i θ})^{2}

(x + 46) (x - 46)

p^{1} (\frac{1}{2} - \frac{( p ^{1} - p ^{2} )}{2 t})

(3 x + 2 y = 0,) (2 x - 3 y = 13,)
