I have this problem, |dw:1360532525098:dw|
And I type it in my calculator like this,
-(3/4)sin(x-(pi/4)) But when I graph it, its on none of my answer choices

Are you in radian mode?
Anyhow, try this graph: http://www.wolframalpha.com/input/?i=y%3D-%283%2F4%29sin%28x-%28pi%2F4%29%29
Yes
also make sure you have the right window to see things so use zoom trig to get a better look (that usually works)
I zoomed in but it shows that the curve cuts through the center, which isnt on any of my choices
it'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
|dw:1360532870601:dw| This is what I get when I zoom in,
you should have something like this |dw:1360533064327:dw|
here's a better look at the actual graph (see attached image)
I no where near got that, did you type the same exact thing I typed in?
yes I typed in (-3/4) sin(x - pi/ 4)
try using 3.14 in place of pi and see if that changes anything
When I typed in exactly what you just wrote it worked, maybe it was my choice of placing the parenthesis?
maybe, hmm wish i could see your calculator before and after, but oh well
glad you got it working though
I can re type what I wrote in & take a picture if you would like?
sure that would be great, thanks
Ah, 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
oh so that would have made x-pi/4 to be -pi/4*x i see now
Yes, if you typed in what I had & instead of using the subtraction symbol & the negative one instead you would of got what I got
yeah I'm getting what you got now, such a small error that I wouldn't have even thought about it lol
Yeah, one small error completely changes the whole graph haha. I noticed it when I was re-typing my problem in & it came out right. Had me confused. Anywho, thank you for help.!
you're welcome
