expand cos(v)(vdy+ydv)

expand

cos (v) (v d y + y d v)

v cos (v) d y + y cos (v) d v

Solution steps

cos (v) (v d y + y d v)

Apply the distributive law:

a (b + c) = ab + a c

a = cos (v), b = v d y, c = y d v

= cos (v) v d y + cos (v) y d v

= v cos (v) d y + y cos (v) d v

\frac{1}{[ s ^{2} ( s + a ) ]}

cos (x + π)

(x + 5) (x - 5)^{''}

(3 x + y) d x + (x + 8 y) d y

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