  • Helpful, but I'm sure most people can get it just by thinking each part through logically

  • @Hellgoregaming yes, all the logical thinking people will have no trouble, i agree.

  • You're a life saver. I'm entering an Engineering program after taking 2 years off from school. I had to take a placement test today and my goal was to test out of algebra, trig, pre-calc, and straight into calculus. Your videos greatly helped me accomplish this, which means I saved $1000's in class fees and at least a year of my time. Thanks so much!

  • @g0tcadaver donations accepted on my website : )

  • Wish me luck! (:

    I've used this video to help me last year and now this year for review!

  • @MoeMonkey78 good luck : )

  • Does the JMT in your name stand for Jedi Mind Tricks?

  • Sooooo helpful

  • @Herman2729 tangents are easy. You know that tan = sin/cos and sin = y and cos = x so just memorize what's shown in this video and if you need tangents just divide the y by the x (y/x). Good luck! :)

  • i need to remember all of that plus tangents in 2 minutes. for my quiz tomorrow

  • This will definitely help me on my trig test

    Greetings all the way from Sweden.

  • I love this video my teacher is full of it don't know how he got his degree

  • I have a trig test today! This will definitely help! Thanks!

  • thank you!!
