SI SESSION 1
22 January 2025
SI- Sai Kaushik
Professor- Dr. Kaya
PHYS 206 UP
Spring 2025
-Ask any questions right now.
-I will be calling on people randomly throughout the semester; just an FYI.
-You can find information about all SIs on the TAMU Academic Success Center website. Navigate to the PHYS 206 page and you should be able to see all the timings and SIs.
-I am not typically supposed to help too much with homework, but I am able to offer some guidance should you need it.
-Only attending SI right before an exam is a waste of time; it is a cumulative effort.
-Feel free to stop me and ask questions at any time.
-I will not be posting solutions. First few sessions do have solutions, but that was because I made the mistake of doing that last semester.
Easy Review Questions
-What is the geometric definition of the integral?
-3 major trigonometric equivalencies?
-Formula for a cross product?
-Solution of quadratic equation?
-Order of magnitude? (ie: pico, nano, … , peta)
Warm Up: Vector Review
-What is the definition of a vector?
-What are some important vectors in physics that you may have heard of?
-What are some properties of vectors?
-What are some non vectorial quantities that you may know of in physics?
-Why is the concept of vectors useful, especially in physics?
-Define what a unit vector is.
-What are i, j, and k with respect to vectors?
-What is a dot product? What is it’s formula?
-What is a cross product? What is it’s formula?
-Result of a cross product is what?
-Meaningful or not meaningful: dot product of a vector and a scalar. What about cross product between the same?
MAIN ACTIVITY: TRIG, PARABOLAS, AND INTEGRALS
Math Review
-Parabolic equations
-What is the general equation for a parabola?
-How can you solve for a value in a parabolic path?
-Solve (5 min):

Trigonometry Review
-Trigonometry is important in PHYS 206
-Physics deals with many important vectorial quantities (velocity, force, field, etc). To resolve the components of a vectorial value, trigonometric functions must be employed (sin, cos, tan, arccos, arcsin, arctan, cot, csc, sec)
-Know Pythagorean formula and how it relates to magnitude
-This will be important once vectors come up again
-You should be able to convert from radians to degrees and vice versa.
-Understand sinusoidal waves
Trig Practice:
Take 5 min.
Units
Units are very important on the exams. Know units from pico (10E-12) all the way to tera (10E12).
-This has come up on every exam in the past few years (except for Fall 24, which means it is likely going to be on Spring 25).
=> You are traveling 500 miles per hour. How many centimeters per second are you moving? Solve in 2 min.
Derivatives and Integrals (5 min)
-Take the derivative of the following expression:
5x^4+sin(35x^2)+ln(5x)
-Take the integral of the following expression:
3x^2(2+x^3)^10 dx
Cool Down: Helpful resources
-Organic Chemistry Tutor Physics I Playlist
-Other SI’s sessions- Generally suggest sticking to UP SIs, but DP may help too.
-For SI, your professor’s SI is usually the best choice because they are tailored to your professor; however, if for whatever reason you decide that you need to attend someone else’s, there is possibly a chance that they may be able to somewhat help you.
-Office hours (particularly recommend Dr. May’s open office hours, where you can just come in and do homework and get help immediately when you need it. He holds office hours 4 days a week for two hours each day)
-Textbook
-TA’s (can email or ask during recitation)
-Past exams
-PHYS 216 PTs
-Khan Academy
