hello, i decided to skip algebra 2 and college algebra entirely, but i have mastered algebra 1 completely and hopefully i do well on this course. but i have a question, is this the full trigonometry lesson? or only some topics are here but many more are missing?
One of the longest if not the longest video I've ever studied on RU-vid. Pushing hard to complete the whole video. I'm at 1:13:17:00, I know I'm getting there. Let's go guys!
Yes, when you factor, you always want the expression to be in terms of the original variable(s) involved. So if you use u or w with a substitution technique, you will need to back substitute when you are done.
Yes, the square root of "a" squared is the absolute value of "a" by definition. In this section in every textbook, we assume all variables represent positive real numbers. I actually mentioned this in the course when we started talking about radicals. sqrt(a^2) = a, if a ≥ 0 sqrt(a^2) = -a, if a < 0
