Thanks! Your response is the one that made the most sense to me. My main confusion was in how to tell whether a condition was true or not, but yours and Simon's explanations made the formulation much clearer. With that in mind I would answer the question in the following way: a) If a number...

Then it appears that statement Y is false? I'm getting really confused. As far as I understood from the book, under a material implication conventionally used in logic, the truth of the statement depends solely on the exclusive truth value of each part (i.e. the truth tables). So it doesn't...

Hi This is a question from my self study of ch.2 of Alfred Tarski's Introduction to Logic Which of the following implications are true from the perspective of mathematical logic? a) If a number x (assuming x is an integer) is divisible by 2 or by 6, then it is divisible by 12 b) if 18 is...

Unless you're aiming at Harvard or Ivy League, then no. I wouldn't get worked up over it if I were you. The quality of education is as good as there, and employers won't care if you got your degree across the border. Keep in mind that only 7% of applications to Ivy League get accepted, so you...

Homework Statement The 1.92 kg physics book shown is connected by a string to a 450.0 g coffee cup. The book is given a push up the slope and released with a speed of 2.58 m/s. The coefficients of friction are μs = 0.457 and μk = 0.166. What is the acceleration of the book if the slope is...

1. A parachustist jumps from an airplane and freely falls y=49.4 m before opening his parachute. Thereafter, he decelerates at a=2.02 m/s2. As he reaches the ground, his speed is 3.11 m/s. How long was the parachutist in the air? For this one I managed to get the solution already using a method...

I'm sorry, I don't really follow. Are you saying that if I find a continuous function equivalent to the continuous parts of the jump function, and integrate it on [a,b], it would equal the integral of the jump function on that same interval? Could you perhaps provide a pictorial representation?

Hi I'm a complete n00b at calculus (first day of the first year) so this question may appear a little...stupid. But I want to hammer into my head every little thing I hear in the lecture hall, so I might as well give it a go. Today the professor explained how jump discontinuities must be...

Hi, I'm a high school physics student and I'm having a lot of trouble with thin film interference Homework Statement A thin layer of oil (noil=1.25) is floating on water (n=1.33). How thick is the oil in the region that strongly reflects green light (λ=556nm)? Homework Equations noil/nwater...
