I have this problem, |dw:1360536452449:dw|
But I entered in my calculator as, 2/3cos((x+)pi/3)) & it says error.
check the (x+)
What do you mean?
you can't have + inside the parenthesis
type this instead (2/3)*cos(x + pi/3)
I did that & then graphed it but it came out a straight line
odd...try replacing pi with 3.14 and see what happens
it sounds like you have the x outside of the cosine, which would explain why you're seeing a straight line
Ah, I had it in degrees instead of radian. Once again another simple mistake haha
oh that would do it lol
I forget to change my settings every now & then oops. But thanks again Jim.!
happens to me all the time, makes me wish there was a way to know which mode it was in
Same, if only ti would make it where it displays the mode at the top some where.
yeah exactly what I was thinking
