解答

展开

e^{(y - \frac{( z - y ) ^{2}}{2 l ^{2} - t})}

e^{y - \frac{z ^{2} - 2 yz + y ^{2}}{2 l ^{2} - t}}

求解步骤

e^{y - \frac{( z - y ) ^{2}}{2 l ^{2} - t}}

(z - y)^{2} = z^{2} - 2 yz + y^{2}

= e^{y - \frac{y ^{2} - 2 yz + z ^{2}}{- t + 2 l ^{2}}}

e x p an d \frac{1}{( z - 2 ) ( z - 1 )}

e x p an d 2 (x - 1) + 3 (x - 2 - 5 (x + 3) = 8)

e x p an d \frac{17 y ^{2} - 119 y + 104}{( 5 y - 3 ) ( y - 5 ) ^{2}}

e x p an d \frac{( 3 + cos ( 4 x ) - 4 cos ( 2 x ) ) cos ^{2} ( x )}{4}

e x p an d \frac{1}{( ( 2 y - 1 ) ( y - 3 ) )}
