What kind of geometry/math topics would I need to succeed in trigonometry?

The source-site ''cheat-sheets'' I include below is an excellent resource for refreshing your rusty skills in trig or algebra (and is quite helpful if/when you take calculus, as well).

Personally, I made a few copies, and I keep the appropriate copies in plastic sheet protectors - for when I tutor students in these topics. As reference sheets, they are almost invaluable - - 95+% of the equations and basic information needed for these classes.

In college, some instructors will allow 'open book' tests - - these are actually more useful than the 'open book' in most cases - - because you don't waste valuable test-time flipping pages or trying to remember where the @#$% information is.

Even for regular studying - very valuable - as you can have the 'cheat-sheet' right beside you as you go through problems - - and not have to flip back to equations in the book.

**Learn** the Unit Circle. There is a ''trick'' I show my tutoring students for remembering the values for sin of the basic angle (and then cos of the angles - - which can then become tan angles!)

Going counter-clockwise from 0 degrees

0 degrees = 0 radians => sin = (sqrt 0)/2

30 degrees = pi/6 radians => sin = (sqrt 1)/2

45 degrees = pi/4 radians => sin = (sqrt 2)/2

60 degrees = pi/3 radians => sin = (sqrt 3)/2

90 degrees = pi/2 radians => sin = (sqrt 4)/2

Cos runs 'backwards' through these.

And tan is sin/cos...

Equations equations equations that's all you need...you just need to remember your algebra that's all you need I took trig this semester and that's all i needed...you get algebra you will get trig as well...hope you do good :)
