dszs Posted June 17, 2014 Share Posted June 17, 2014 Hi, I was just wondering about some stuff about sine wave when I was reading the expression cookbook. The expression written there was : sin ( $T * frequency ) * amplitude + offset So, what does the $T represent in the equation. Sorry if this seems like a noob question, I tried experimenting but yet to see any pattern to it. Many thanks! Darren Quote Link to comment Share on other sites More sharing options...
briank1458 Posted June 17, 2014 Share Posted June 17, 2014 Hello, $T represents Time (in seconds). So I believe frame 24 == 1 (if you're doing 24fps). Quote Link to comment Share on other sites More sharing options...
Skybar Posted June 17, 2014 Share Posted June 17, 2014 $T is Time, yes. Almost the same as $FF/24 (or whatever your framerate) - with the difference that $T is 0 at frame 1, and $FF then is 1 of course. Quote Link to comment Share on other sites More sharing options...
