expand cos(x-y)(1-(dy)/(dx))

expand

cos (x - y) (1 - \frac{d y}{d x})

cos (x - y) - cos (x - y) \frac{d y}{d x}

Solution steps

cos (x - y) (1 - \frac{d y}{d x})

Apply the distributive law:

a (b - c) = ab - a c

a = cos (x - y), b = 1, c = \frac{d y}{d x}

= cos (x - y) \cdot 1 - cos (x - y) \frac{d y}{d x}

= 1 \cdot cos (x - y) - cos (x - y) \frac{d y}{d x}

Multiply:

1 \cdot cos (x - y) = cos (x - y)

= cos (x - y) - cos (x - y) \frac{d y}{d x}

2 (6 - \frac{4}{3}) π

u (2, 0) v (3, - 4)

\frac{x}{( 2 x + 1 ) ^{2}}

\frac{s + 2}{( s + 3 ) ( s + 4 )}

\frac{d ^{2} y}{( d x ) ^{2}} (x^{2} + y^{2} = 1)
