推 shinyhaung:哎呀 又搞笑了XD 看來我該去睡覺了 11/15 22:29
→ mdpming:我跟一樓一樣.... 11/15 22:38
→ cfdco:是要找fourier transform喔 11/15 23:13
推 shinyhaung:(2/ω)sinωx-(2/ω)cosω+(1/ω^2)sinω ?? 11/15 23:20
→ shinyhaung:後面兩項還要加個i上去 11/15 23:20
推 CRAZYAWIND:我算出來是 11/16 01:54
→ CRAZYAWIND:(-2i/w)cosw + (2/w)sinw + (2i/w^2)sinw 11/16 01:56
