expand (x-pi/4)sin(2x)

expand

(x - \frac{π}{4}) sin (2 x)

x sin (2 x) - \frac{π}{4} sin (2 x)

Solution steps

(x - \frac{π}{4}) sin (2 x)

= sin (2 x) (x - \frac{π}{4})

Apply the distributive law:

a (b - c) = ab - a c

a = sin (2 x), b = x, c = \frac{π}{4}

= sin (2 x) x - sin (2 x) \frac{π}{4}

= x sin (2 x) - \frac{π}{4} sin (2 x)

(d t + t^{7} d w)^{2}

(- 14, - 6) y (- 12 y^{22})

(4 x^{3} y - 15 x^{2} - y) d x

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

(3 y d x + 6 d x - x d y = 0) \frac{1}{x d x}
