Topic: Need help thanks
hey guys im new with this program and im trying to plot
y=10sin(pi/6x+50.025pi/9)+42.85426351
it should look like a normal sin graph
(its on graphamitica)
but this looks like..
(on graph 4.3)
anyone know what im doing wrong?
thanks so much

Did you read the error message?
It tells you that you cannot write a parameter after a constant. This means that pi(2) does not work. Use pi*(2) instead.
helped me out
work like this
10sin(pi*(1/6)x+50.025pi*(1/9))+42.85426351
