expand δ/(δx)(cos(x)+cos(y))

expand

\frac{δ}{δ x} (cos (x) + cos (y))

\frac{δ}{δ x} cos (x) + \frac{δ}{δ x} cos (y)

Solution steps

\frac{δ}{δ x} (cos (x) + cos (y))

Apply the distributive law:

a (b + c) = ab + a c

a = \frac{δ}{δ x}, b = cos (x), c = cos (y)

= \frac{δ}{δ x} cos (x) + \frac{δ}{δ x} cos (y)

\frac{( x + 3 i ) ^{5} \cdot ( 3 - 4 i )}{16}

\frac{650}{0.25} \cdot ((1 + \frac{1}{400})^{(12 \cdot 29)} - 1)

w^{2 (n + 1)}

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

\frac{x + 1}{( x - 8 ) ^{2}}
