On page 180 in Exploring Creation with Physics 2nd Edition, the author multiplies T1 times cos(45. He comes up with 0.707 times T1. When I do this on my calculator, I invariably come up with zero! (However, I could not figure out how to enter the 1 on my calculator as it is represented in the problem; that is, as an exponent, but situated at the bottom of the number. It is supposed to mean T1, as in Tension 1. There are two points of tension in the problem. ) Could someone please explain the steps the author took to achieve that answer? Thank you!
