Oh yes. I sure do have the 20-20 vision. After a very exhausting 7:00 – 4:00 Monday class, I totally misread a problem in Peterson’s Calculus with Analytic Geometry book when I was reviewing for a test last night. Mom even said, “For the 22 years that I have taught Mathematics and Geometry, this is the first time I have encountered a circle being tangent to ‘both sexes'”
What a life.
