Question about Office Equipment & Supplies
When plotting functions like "sin x", i should get a graph starting at zero, peaking at pi/2, zero at pi, low point in 3pi/2 and zero again at 2pi. (Wave going up, down, up) Instead its behaving like the function "-sin x" doing the opposite. (Wave going down, up, down). Does anybody know if this is caused by a setting? Amplitude, phase and ordinary frequency shows correctly, so the only problem is that is behaves as a negative wave instead of a positive.
