    Mr. Hanson, you are a blessing to many engineers across the country and I want to thank you personally for all you have done within this playlist. Your teachings are opening a new avenue of learning that I did not think was possible for myself. I have always struggled with this topic in my engineering classes, yet you can break things down in such a way that everything becomes simplistic and commonsensical. I hope you realize how much we as students appreciate your lessons and I also hope you and your family are doing well during this pandemic. Thank you for all you have done! - Texas A&M Engineering Student

    Took a long break from trig / math in general when I dropped out. One video got me caught up for the semester, saved me much headaches. Thank you, Mr. Hanson, you're truly a gem.

    DR. Hanson, thank for a powerful review of Trigonometry and The Triangle Rule for Adding Vectors. These classic concepts are very important to the development of Statics. All students should do a deep review of Algebra ,Geometry, Trigonometry and Calculus one before enrolling in Statics.

    Dr. Hanson, while I appreciate the content and frequency of your videos. In this particular video, you said something that was/is offensive. The supplemental trigonometry rule referenced as the hood rule. The decision to do so was in poor taste as the engineering field itself is not seen as a culturally inclusive field. You have to be cognizant as well as careful that your platform does not exclude or marginalize anyone.

      Ramiro Sandoval, I care that is who. If you live in the same world we all live in, you understand why the statement is offensive. Idk where you come from and don't really care, but your name is representative of someone who is of Hispanic descent. If he said something that was disrespectful to your culture which has a very low percentage of engineers as well hopefully you would speak up.
