1.6. Exercises P1.1 Using Cartesian bases, show that (u Ä v) ⋅ (w Ä x) = (v ⋅ w)u Ä x where u, v, w, and x are rank 1 tensor. Solution: Using the Cartesian basis, ( )( ) ( )( ) i i j j k k l l u Ä v w Ä x = u e Ä v e ⋅ w e Ä x e . Since the dot product occurs between adjacent bases, we have ( )( ) ( )( ) ( ) ( ) ( ) ( )( ) i i j j k k l l i j k l j k i l i j k l jk i l i j j l i l j j i i l l u v w x u v w x u v w x u v w x v w u x d Ä ⋅ Ä = ⋅ Ä = Ä ...

Exam (elaborations) TEST BANK FOR An Introduction to Modern Astrophysics By Carroll B.W. and Ostlie D.A. (Solution manual) CHAPTER 1 The Celestial Sphere 1.1 From Fig. 1.7, Earth makes S=P˚ orbits about the Sun during the time required for another planet to make S=P orbits. If that other planet is a superior planet then Earth must make one extra trip around the Sun to overtake it, hence S P˚ D S P C 1: Similarly, for an inferior planet, that planet must make the extra trip, or S ...

UPDATED 2023 VERSION HESI A2 PHYSICS QUESTIONS & ANSWERS (SCORED A+) HESI Physics Questions with Answers and Explanations 1. When a junked car is compacted, which statement is true? A. Its mass increases. B. Its mass decreases. C. Its density increases. D. Its density decreases. Explanation: Since density = mass/volume, it should be obvious that the decrease in volume as a car is crushed should lead to an increase in density. Nothing happens to change the mass of the car. 2. A...

Factor Based Models classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model Why limit number of factors in a model? 2 reasons overfitting: when # of factors is close to or larger than # of data points. Model may fit too closely to random effects simplicity: simple models are usually better Classical variable selection approaches 1. Forward selection 2. Backwards elimination 3. Stepwise regression greedy algorithms...
