expand (pij)/(z(z-pi-pij)(z+pi+pij))

expand

\frac{πj}{z ( z - π - πj ) ( z + π + πj )}

\frac{πj}{z ^{3} - π ^{2} z - 2 π ^{2} j z - π ^{2} j ^{2} z}

Solution steps

\frac{πj}{z ( z - π - πj ) ( z + π + πj )}

Expand

z (z - π - πj) (z + π + πj) : z^{3} - π^{2} z - 2 π^{2} j z - π^{2} j^{2} z

= \frac{πj}{z ^{3} - π ^{2} z - 2 π ^{2} j z - π ^{2} j ^{2} z}

cos (x) \cdot (1 + \frac{tan ^{2} ( x )}{sec ( x ) + 1})

(2 - 4 x - 3) (2 + 4 x - 3)

(x^{\frac{1}{p}} + y) (x^{\frac{1}{p}} + 8 y)

(sin (x) + tan (x)) (cos (x) - cot (x))

\frac{( x + 1 ) ( x - 2 )}{( x + 2 ) ( x - 4 )}
