integral of [(2t-1)i+4t^3j+3sqrt(t)k]

Lösung

\int [(2 t - 1) i + 4 t^{3} j + 3 t k] d t

i (t^{2} - t) + j t^{4} + 2 k t^{\frac{3}{2}} + C

Schritte zur Lösung

\int (2 t - 1) i + 4 t^{3} j + 3 t k d t

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int (2 t - 1) i d t + \int 4 t^{3} j d t + \int 3 t k d t

\int (2 t - 1) i d t = i (t^{2} - t)

\int 4 t^{3} j d t = j t^{4}

\int 3 t k d t = 2 k t^{\frac{3}{2}}

= i (t^{2} - t) + j t^{4} + 2 k t^{\frac{3}{2}}

Füge eine Konstante zur Lösung hinzu

= i (t^{2} - t) + j t^{4} + 2 k t^{\frac{3}{2}} + C
