合并 2sin(pi/4 (x-3))+4

解答

合并

2 sin (\frac{π}{4} (x - 3)) + 4

2 sin (\frac{π ( x - 3 )}{4}) + 4

求解步骤

2 sin (\frac{π}{4} (x - 3)) + 4

乘

\frac{π}{4} (x - 3) : \frac{π ( x - 3 )}{4}

= 2 sin (\frac{π ( x - 3 )}{4}) + 4

e x p an d \frac{d z}{( z ^{2} + 4 ) ^{2}}

e x p an d \frac{( 16 x ^{2} - 1 ) ( 16 x ^{2} - 1 )}{64 x ^{2}}

e x p an d \frac{\partial}{\partial y} (4 e^{y}) + e^{y} (2 x + 4 y)

\frac{d}{d t} ((x) (2 sinh (t) + 3 t^{2}))

e x p an d \frac{( x ^{n + 1} - ( n + 1 ) x + n )}{x - 1}
