- Yesss! This will be easy! It'll bring my grade up!!
- TRIGONOMETRY REVIEW!
- Really...since when do have a test...I know nothing...
- Good morning! Today we are going to be reviewing for our test tomorrow!
- This is light work!
- tan30=a/7(7)7tan30=a4.04=a
- Solve for a
- a
- 7
- 30
- Okay...I guess i'll give it a try...
- Remember!SOH= sin0=opp/hypCAH= cos0=adj/hypTOA= tan0=opp/adj
- Let's start with something simple.
- tan30=a/7(7)7tan30=a4.04=a
- LAW OF SINES:
- Laws of sines will be part of your test so copy down the example if you don't have it already.
- 10/sin33= a/sin58 - asin33=10sin58asin33/sin33=8.48/sin33a=15.57
- a/sinA=b/sinB= c/sinC
- Remember: a, b, c are the sides and sinA,sinB, sinC are the angels.
- a
- 33
- 58
- 10
- I know this by heart! For 30 its 1/2√3/2√3/360 is√3/2 1/2 √345 is √2/2√2/2 1
- 306045S1/2√3/2√2/2C√3/21/2√2/2T√3/3√31
- I also know it by heart! It might be the only thing I know.
- Who remembers the 30, 60, 45 chart? Camila? Mario?
- Great job both of you! Camila how did you know where to draw the arrows? And Mario how did you get your answers?
- Camila and Mario you each will do one problem up on the board.
- 2sinx +1 =0 -1-12sinx/2=-1/2sinx =-1/2x=210x=330
- Trig Equations Practice Problems:
- Since the sinx was negative I did the opposite of sign in the graph which was tan and cos.
- 30
- cosx+1=0 -1 -1 cosx=-1 - x=180
- 30
- cosx(cosx+1)=0
- cosx=0 - x=90,270
- cos ^(2)x+cosx=0
- I knew that x was cos and y was sin so I looked for where y was 0 and where y was -1.
- (0,1)
- (-1,0)
- (0,-1)
- (1,0)
- The Next Day....
- 100%
- I GOT 100! YESSSSS!
- TEST TODAY! GOOD LUCK CLASS!
- 95.5%
- I PASSED WITH AN A+!... and I thought I was going to fail!
