SINE COSIE 3 ruler set that can draw a beautiful sine wave. If you difficult to drawing a beautiful sine wave on a notebook, or if you want to write the voltage of an AC motor correctly? I made a ruler for drawing a sine wave with a 3D printer. It is a set of 3 piece sin θ, sin 2θ, and 1 / 2sin θ. The basic sine wave (sinθ yellow) was created with a width that allows 1.5 wavelengths to enter the B5 notebook. The scale is put every 15 °, and 1mm is set to 3 °, so the intervals are 5mm. The amplitude is 30 mm, and the width from the highest point to the lowest point is 60 mm. For sin 2θ (orange), 1 mm is 6 °. 1/2 sin θ (light blue) has an amplitude of 15 mm. The total length of the ruler is 180 mm, which is the same for all three rulers. Since the scale is dented, if you do not tilt it outward when drawing along the pencil, the line will rattle at each scale, but if you get the hang of it, you will be able to draw it neatly. I think you will learn various ways to draw a sine wave (sine curve), but for the time being, how about those who want to draw a sine wave quickly and beautifully? The video introduces the usability.
