Click For Summary
The discussion centers on a potential typo in the textbook "Understanding Symbolic Logic" by Virginia Klenk, where a 'T' is incorrectly placed at the bottom of a diagram instead of an 'F'. Participants confirm that the highlighted text in the book is accurate, but the diagram contains this error. The confusion arises from the contradiction between the formula being labeled as false and the presence of the 'T'. Verification from peers helps clarify the misunderstanding. The consensus is that the 'T' is indeed a typo.

It's possible that I'm not understanding the diagram and their reasoning, but I wanted to check with some people here before I come to a conclusion.

The Attempt at a Solution



I don't understand why the book says the formula is false, yet there is a "T" at the bottom of the computation.

The book is, Understanding Symbolic Logic, 5th ed. by Virginia Klenk.

The 'T' at the bottom of the diagram is a typo. It should be an 'F'. The words you highlighted are correct.

Thank you for verifying, Stephen.
 

Thread 'Distance between a Clock's hands when the distance is increasing most rapidly'

Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
