expand (x+5)cos(x)

Solution

expand

(x + 5) cos (x)

Solution

x cos (x) + 5 cos (x)

Solution steps

(x + 5) cos (x)

= cos (x) (x + 5)

Apply the distributive law:

a (b + c) = ab + a c

cos (x) (x + 5) = cos (x) x + cos (x) \cdot 5

= cos (x) x + cos (x) \cdot 5

= x cos (x) + 5 cos (x)

\int \frac{x ^{2}}{196 - x ^{2}} d x

y^{''}+2y^'+37y=0,y(0)=-3,y^'(0)=21

y^{^{''}} + 2 y^{^{'}} + 37 y = 0, y (0) = - 3, y^{^{'}} (0) = 21
