  What an AWESOME video!!!! I've been a long time subscriber and come to your videos when I need to really understand a concept. Haven't been in quite some time but I'm taking MTH 162 (precalc II) this summer semester at community college and I think google is spying because as soon as I finished some orientation stuff your video popped up and honestly I can't be mad because it was right on time and exactly the subject I needed. I remember this subject so well from high school but it takes some practice to get back into the hang of things! Great teaching skills, I think everybody is somewhat of a visual learner so it helps to see the elevation & depression concepts as drawings! If I could take a pic of my notes and send them I think you'd be happy! ahaha Can't wait to watch solving right triangles later tonight! Keep them coming.. it'll be a long summer!

  It is incomprehensible to me how a shape such as a triangle can be so important in math when in reality we don&apos;t even see them in our daily life. We only get to see them a math classes. Correct me if I&apos;m wrong.

  Thank you so much. I&apos;ve loved your videos since the very start, and &nbsp;I appreciate all of your help. I love math in general, and started taking advanced Algebra 2 in 8th grade, and I love it, but trignometry makes no sense at all. Thank you very much because you just saved my grade, and my happiness.
