  • Thanks so much for this lesson you saved my ass for my Cosine test

  • Im starting to like your lessons! really healpful..!

    By the way.. for the scientific calculator you dont need to calculate first the left side and then the right side, you can put everything in and just press equal. It gives you the right answer.

  • this is really helpful :)

  • thanks
