expand u(t-pi)cos(t)

expand

u (t - π) cos (t)

u t cos (t) - π u cos (t)

Solution steps

u (t - π) cos (t)

= u cos (t) (t - π)

Apply the distributive law:

a (b - c) = ab - a c

a = u cos (t), b = t, c = π

= u cos (t) t - u cos (t) π

= u t cos (t) - π u cos (t)

5 c^{2} d e (9 c d^{2} - 7 c d + 4 e)

\frac{1}{( y ^{2} - 1 ) ( e ^{y} - 2 )}

2 (2 x - 3 y = - 19)

C (3, - 5)

(x - 3) \cdot (2 x - 5 = 0)
