expandir (2x+y)(cos(t))+(2y+x)(e^t)

Solução

expandir

(2 x + y) (cos (t)) + (2 y + x) (e^{t})

2 x cos (t) + y cos (t) + 2 e^{t} y + e^{t} x

Passos da solução

(2 x + y) (cos (t)) + (2 y + x) (e^{t})

= (cos (t)) (2 x + y) + (e^{t}) (2 y + x)

Expandir

(cos (t)) (2 x + y) : 2 x cos (t) + y cos (t)

= 2 x cos (t) + y cos (t) + (2 y + x) (e^{t})

Expandir

(e^{t}) (2 y + x) : 2 e^{t} y + e^{t} x

= 2 x cos (t) + y cos (t) + 2 e^{t} y + e^{t} x

\frac{5 ( x - 3 ) ^{5}}{16}

\frac{( x + 1 ) ( - x + 10 )}{2}

e^{- 2 (x + y i)}

6 (x^{2} + 2 x + 2)^{2}

\frac{5 x + 20}{( x + 2 ) ^{3}}
