Question about Geometry and Trigonometry





jabronie25
School is coming to an end. And i took Algebra 2 this year. (Sophomore in Highschool)

So my question is: Do you need to know some Geometry in order to learn Trig?

Cuz i can take Trig or Geo next year. Im heading towards Trig, tho i dont have a single knowledge in Geo

Essentially, no - you will probably need some very basic knowledge of geometry...but only stuff that is pretty much self explanatory...

That having been said, if you are interested in maths and want to study it i recommend you do both as they are both essential courses.

I'd have to go with yes... but just basic geometry. be familiar with the pythagorean theorem (very basic), 30 60 90 triangles, and 45 45 90 triangles... that's about all. you need to know those two triangles because you will find that the unit circle is derived from those triangles and the unit circle is the biggest part of trig....
