expand (t-a)^2+e^{-at}-2cos(at)

expand

(t - a)^{2} + e^{- a t} - 2 cos (a t)

t^{2} - 2 t a + a^{2} + e^{- t a} - 2 cos (t a)

Solution steps

(t - a)^{2} + e^{- a t} - 2 cos (a t)

= (t - a)^{2} + e^{- t a} - 2 cos (t a)

(t - a)^{2} : t^{2} - 2 t a + a^{2}

= t^{2} - 2 t a + a^{2} + e^{- a t} - 2 cos (a t)

ln (x) (x - 1)^{2}

\frac{2}{5} y - \frac{3}{10} y

(5 i, 3 j, 2 k) (- 4 i, - 1 j, - 5 k)

\frac{1}{( s + 2 ) ( rcs + 1 )}

\frac{64 x ^{2} - 80 x y + 25 y ^{2}}{( - 10 x + 10 y ) ( - 4 x + y )}
