- things i need to revise for before friday’s trigonometry, matrices, proof by induction test the revising lesson for (spec) trig revision
review:
pmod 2022 test 4 matrices and trig
- get this checked
onenote revision stuff:
- from doing the practice revision stuff on onenote
- remember +- when squaring!!!
- ask about question 4a chapter 9
pmod 2020 test 3 matrices and trig
- 2.2.3 matrices,
- 2.1.7 general solution,
- 2.1.4 graphing sec functions,
- 2.2.3, 2.1.3 - matrix solving (see question 3), ask dr pearce about it!
-
wait nvm i got it basically the range is given in the question ! :p
-
- 2.1.3 2.1.5 - trig proof, matrix anticlockwise rotation
old
general
- plus and minus when squaring :(
trig
- cosine form = acos(b(x-c)) + d,
- factorising notice when you should,
- CAST error,
- sum to product,
- product to sum,
- finding function of a sine + cosine function, sine + sine, cosine + cosine etc
- cambridge assumes there is no phase shift, how do you calculate if there is phase shift? (low priority, probably not on the test)
- graphing tan, transforming tan
- graphing cosec, sec, transforming cosec sec etc
- factor theorem (low priority might not be in the test)
matrices
- using matrices to solve for intersection
