expand e^4t(t-cos(t))

expand

e^{4} t (t - cos (t))

e^{4} t^{2} - e^{4} t cos (t)

Solution steps

e^{4} t (t - cos (t))

Apply the distributive law:

a (b - c) = ab - a c

a = e^{4} t, b = t, c = cos (t)

= e^{4} tt - e^{4} t cos (t)

e^{4} tt = e^{4} t^{2}

= e^{4} t^{2} - e^{4} t cos (t)

(r cos (θ) + i r sin (θ))^{3}

\frac{d ^{2}}{d x ^{2}} ((y) (e^{x^{2}} + sin (3 x + 1)))

(6 e - 3 f - 4) \cdot 2

\frac{x ^{2} - y ^{2}}{( x ^{2} + y ^{2} ) ^{2}}
