Trigonometry Review (2 of 5)

[Halfpipesk8r]

number 19 was supposed to be (2radical 5) over 5, not (2radical 5) over 2.

@Halfpipesk8r You are right. In my hurry to rationalize, I used the 2 instead of 5. The Tanx= 2rt(5)/5.

@Halfpipesk8r I've corrected this now with an annotation. Thank you!

Wow! I learned Trig in an hour. Thank you so much for these videos :)

[davidtutorsmath]

@sacae95 You're quite welcome! While I wouldn't say that cramming is the best way to learn trig, I'm glad that you now feel confident with it.

sir in no 16 i think it should be negatine square root of three am i correct?

[davidtutorsmath]

@MrKriminal27 While I do make plenty of mistakes (and I welcome corrections), #16 is correct as -rt(3)/3. Double check that you took the cotangent.
