  • 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!
