Best ResponseYou've already chosen the best response.0Anyhow, try this graph: http://www.wolframalpha.com/input/?i=y%3D%283%2F4%29sin%28x%28pi%2F4%29%29

Best ResponseYou've already chosen the best response.1also make sure you have the right window to see things so use zoom trig to get a better look (that usually works)

Best ResponseYou've already chosen the best response.0I zoomed in but it shows that the curve cuts through the center, which isnt on any of my choices

jim_thompson5910

Best ResponseYou've already chosen the best response.1it's not supposed to cut through the center because of the phase shift that moves it to the right a bit normally sine graphs go through the origin, but not this one

Best ResponseYou've already chosen the best response.0I no where near got that, did you type the same exact thing I typed in?

Best ResponseYou've already chosen the best response.1yes I typed in (3/4) sin(x  pi/ 4)

Best ResponseYou've already chosen the best response.1try using 3.14 in place of pi and see if that changes anything

Best ResponseYou've already chosen the best response.0When I typed in exactly what you just wrote it worked, maybe it was my choice of placing the parenthesis?

Best ResponseYou've already chosen the best response.1maybe, hmm wish i could see your calculator before and after, but oh well

Best ResponseYou've already chosen the best response.0Ah, my apologies, I typed in mine ( (3/4)sin(x(pi/4)) ) & I used the negative sign instead of the subtraction sign between the x & pi

jim_thompson5910

Best ResponseYou've already chosen the best response.1oh so that would have made xpi/4 to be pi/4*x i see now

Best ResponseYou've already chosen the best response.0Yes, if you typed in what I had & instead of using the subtraction symbol & the negative one instead you would of got what I got

Best ResponseYou've already chosen the best response.1yeah I'm getting what you got now, such a small error that I wouldn't have even thought about it lol

Best ResponseYou've already chosen the best response.0Yeah, one small error completely changes the whole graph haha. I noticed it when I was retyping my problem in & it came out right. Had me confused. Anywho, thank you for help.!
