expand cos(3t)h(t-2pi)

expand

cos (3 t) h (t - 2 π)

t h cos (3 t) - 2 πh cos (3 t)

Solution steps

cos (3 t) h (t - 2 π)

= h cos (3 t) (t - 2 π)

Apply the distributive law:

a (b - c) = ab - a c

a = cos (3 t) h, b = t, c = 2 π

= cos (3 t) h t - cos (3 t) h \cdot 2 π

= t h cos (3 t) - 2 πh cos (3 t)

3^{3} \cdot 3

(D^{2} + 9) y - e^{4 x}

[- \frac{3}{4} + \frac{3}{2 ( t ^{4} + 2 )}]

sin (t) (h) (t - 2 π)

D x (\frac{cos ( x )}{ln ( x )} - 1)
