shinking sineA typical sine wave will shink by 2 in x and y dimensions if squared. igloo myrtilles fourmis #2 20060304 05:15:37
Re: shinking sineOh yes, an amplitude of 2 which is a sine wave that varies from 2 to 2 in its height. igloo myrtilles fourmis #3 20060304 07:19:36
Re: shinking sineAlso if you square a sine or cosine wave that is shifted up or down any amount, then the resulting shape is no longer a sine or cosine wave shape, it is misshapen. I plotted a lot of examples to see this. igloo myrtilles fourmis #4 20060304 07:37:56
