What’s the difference between disk method, washer method and shell method in calculus?

- The disk method is when you apply cal to the surface of a retroreflector, such as on a stop sign. You want to use this method when visibility at night is reduced and it’s difficult for drivers to see their surroundings.
- The washer method is typically used in foggy or snowy weather, with an eye dropper if necessary. It allows more precision and usually doesn’t leave a mess behind. Apply 3-4 drops of cal onto your window washers so that the liquid drips down 2 inches or so off the bottom of the wiper blade and starts dripping off onto your windshield wipers below – just enough so there’s some buildup but not too much where it will spill all over the place.
- The shell method is when you rub cal all over a rubber membrane. This method is best used in dry weather and exclusively on cars without rain sensors and automatic wipers so you can get your fun little show started right away. Apply enough pressure to the membrane so that your finger sinks into it slightly and apply 4-5 drops of cal onto your car’s hood. If you’re feeling extra sloppy, go ahead and make it 6. It will be messy but worth it in the end with a big pretty white mess for all to see.
