expand s/((s^2+a^2)(s^2+b^2))

expand

\frac{s}{( s ^{2} + a ^{2} ) ( s ^{2} + b ^{2} )}

\frac{s}{s ^{4} + b ^{2} s ^{2} + a ^{2} s ^{2} + a ^{2} b ^{2}}

Solution steps

\frac{s}{( s ^{2} + a ^{2} ) ( s ^{2} + b ^{2} )}

Expand

(s^{2} + a^{2}) (s^{2} + b^{2}) : s^{4} + b^{2} s^{2} + a^{2} s^{2} + a^{2} b^{2}

= \frac{s}{s ^{4} + b ^{2} s ^{2} + a ^{2} s ^{2} + a ^{2} b ^{2}}

\frac{1}{( 1 + x ) ^{3}}

cos (θ) (csc (θ) - sec (θ)) + 1

A (4, - 1) B (2, 3) C (1, 3)

(- 1 + i)^{5}

(4 sin (x) + 4 cos (x))^{2}
