Dear group, I cannot figure out why the calculations inside [expr (x*cos(theta))-(y*sin(theta));(x*sin(theta))+(y*cos(theta))] gives me wrong results. The above mentioned formula for rotation is correct. I initialize the values through [value] object before preforming computation. The initial values are: x=1, y=0, theta=1/2pi. I expect the new x and new y to be (0,1) respectively after the rotation. But, for some reason, I get (-1,1). I checked the help files for [value] and [expr] and it looks like I am doing everything right. Anyone have an idea where's the mistake?Thank you!Hrvoje Radnic https://www.instagram.com/singlecycled/ https://pdvrecords.bandcamp.com/album/umovi-protiv-valova https://soundcloud.com/sumovi-protiv-valova 00385(0)915225162 --- [email protected] - the Pure Data mailinglist https://lists.iem.at/hyperkitty/list/[email protected]/message/FVTCX5A323GUEEZXZWNLAY5YFNK7GP74/ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://lists.iem.at/
