erweitern (4x^2+5y^2)i+3xyj

Lösung

erweitern

(4 x^{2} + 5 y^{2}) i + 3 x y j

3 j x y + (4 x^{2} + 5 y^{2}) i

Schritte zur Lösung

(4 x^{2} + 5 y^{2}) i + 3 x y j

= i (4 x^{2} + 5 y^{2}) + 3 j x y

Schreibe

i (4 x^{2} + 5 y^{2})

um:

4 x^{2} i + 5 i y^{2}

= 4 x^{2} i + 5 i y^{2} + 3 j x y

Rewrite in standard complex form:

3 j x y + (4 x^{2} + 5 y^{2}) i

= 3 j x y + (4 x^{2} + 5 y^{2}) i

e x p an d 2 (x y)

\frac{\partial}{\partial y} ((z) (7 x + 8 y^{2}))

e x p an d - \frac{6}{( x - 3 ) ^{2}}

e x p an d (x - 2 + 8 i) (x - 2 - 8 i) (x - 4) (x - 1) (2 x - 1)

e x p an d (p e^{b x} + n e^{- b x}) cos (a x)
