Adv Functions Quizzes

Break the system. Know how the quizzes work exactly. Quizzes are every Friday, multiple choice or true and false always.

Tangent

When you see a table - Graph it

This is because when you use a table, the intervals are too big. A graph also helps you see the flow of the graph.

Factoring

Whenever you want to sub in something into a formula, you must say: ā€˜letā€™ f(x) = [whatever the formula is] then, f(92193912) = [the equation with the subbed in value]

Intervals

  • Always remember the x āˆˆ ā„
  • Use Chart Making for intervals
  • Test with big numbers for testing intervals
  • NEVER cancel out variables. Even if you get the correct answer, if you cancel the variables, you will lose marks

Rationals

Chap 3 Solving Processes

Graphing

  • Donā€™t make your asymptotes look wobbly. Make sure it approaches.
  • You need the asymptote lines on the graph.

Reciprocals And Rationals

Equalities & Inequalities

  • State restrictions!
  • When it asks you to check, make a chart
Inequalities
  • Donā€™t cancel out the denominator. You donā€™t know if its a negative flip or not.

Obliques

  • Write answers in radical form. WITH THE root!

Trigonometry

Radians

  • Always rationalize
  • Try to turn the perfect squares into the (x)^2 version
  • Do not show L.S = R.S before you prove it.
  • He marks if you draw a diagram. So draw a diagram of the angle if they give you it
  • ā€˜let x = some angleā€™ when you want to use variables to substitute angles

Graphing Trig

  • Amplitude is ALWAYS POSITIVE! y = -2sinx. amplitude is 2. BUT. a is NOT same as amplitude. you can say a is negative. NEVER SAY amplitude is negative

Solving Trig Equations

  • Check the interval they want your solution in
  • Write answers in 4 decimal places

Double Angle

  • If you have something like 2x = 1.11979515, then you can also add 2pi to 2x and get 2 more answers.

Tides

  • Tide coming in = positive sine graph
  • Sea level is not exactly 0

Rates of Change

  • Dont round the decimals down

Logarithm

  • A function with a vertical stretch will not be equal to a function with a similar horizontal stretch. like, these 2 graphs go at the same point, but they are not the same
  • We will always get part of the equation. Finding equation from graph is too difficult
  • You will have to prove
  • Be sure to bring heaven down to earth Change of Base Theorem

unit 6 and 7 have 2 attempts on bright space

When they say ā€˜Solveā€™ YOU MUST ALWAYS ā€˜Checkā€™

State restrictions. He is not fair
