Webpower, and its axis). In contrast, a power cross simply states the power of two. cylinders—no spherical power is implied. This states ‘the entire lens has a base power of +3, and +2 of cylinder power. with axis 090 has been added.’ (Note that this means the lens has a total of +5D power at axis 090--the base +3 plus the cylindrical +2.) 13 WebGenerally one will be simpler than the other. If you are integrating over a sphere or a cylinder, the choice is obvious. If it’s something like a cone, spherical is generally easier (try finding the volume of a cone with a flat top and you will see what I mean). However, either coordinate system can be used for any problem. how to start ipad without passcode
