# I have a textbook question about finding the value of an angle

## Top Questions

uction in Algebra II. I need someone to tutor me through the initial material. We are using the textbook Big Ideas Math, Algebra II, a Common Core Curriculum, copyright 2015.

ition by Arnold J. Insel, Lawrence E. Spence, and Stephen H. Friedberg. I feel like the textbook lacks explanation considering this is my first exposure to linear algebra. At this point in the semester, I feel like I have a good idea of the concepts and how to represent them (e.g. I understand and can visualize what is happening in space) because I've spent a lot of time learning from alternative resources. What I am having trouble with now is when I go back to the book, I can follow the examples to an extent, but there are computations that aren't explained and I don't know where they are coming from. Moreover, and more importantly, I don't know how to approach the assignment questions at all.

I am in desperate need of help. There questions are in accordnce wih the AUDITORY CORTEX 1. How is sound intensity encoded? (I am not sure if these means how is it measured...?) What is a rate level function? What is the tonotopic map of the cochlea? What is a tuning curve ? What is the best frequency? What is the threshold ? What is the Volley Theory? I have an idea of the material since it was review in class but the PowerPoint slides are hard to understand. 2. Describe the concept of sound localization and the coincidence detection model of binaural processing occuring in the superior olivary nucleus that mediates sound source localization? (I don't even know where to start with that one) 3. Distinguish between the neural circuit processing intetnaural time differences intetnaural level differences? How and where are the signals compared? (I understand the level vs time difference but I do not know about the neural circuit processing... And what does it mean by where are the signals compared?) 4. Understand the gross organization of the auditory cortex: primary AI and secondary AII auditory cortex, tonotopic organization. I am using the textbook brain and behavior 4th edition by Bob Garrett and also the review PowerPoint slides given to the class but it is mostly charts and graphs
