This formula by a famous Greek mathematician can only be used in right triangles.
What is the Pythagorean Theorem?
You use this form for the equation of a straight line when given the gradient and the y-intercept. (Give the actual formula)
What is slope-intercept form? y = mx + b
The logically symbol for this compound statement looks like this =>.
What is an implication (conditional statement)?
You do 2nd - trace - 5 to get this; just make sure to press enter 3 times!
What are the coordinates of the intersection?
The asymptote for these is always y = c, where c is the constant in the equation that looks like a y-intercept but isn't.
What are exponential functions? (e.g. y = 2^x + 5... asymptote: y = 5)
This trig rule is used in triangle questions when given two sides and the included angle.
What is the cosine rule? or law of cosines?
You get this statistic by going to Stat -> Calc -> LinReg(ax+b)... just make sure StatDiagnostics are on!
What is the correlation coefficient (r)?
The split branches within a tree diagram each have to add up to this.
What is 1? (e.g. 1/2 + 1/2 = 1)
If there is a maximum or minimum point, then this equals zero.
What is the derivative? (Deduct 200 if they said "x")
You use this rule when finding the derivative of a polynomial function in the form y = ax^n.
What is the power rule? dy/dx = anx^(n-1)
This formula is used to find the volume of a cylinder.
What is V = (pi)(r2)(h)?
You use this function of the calculator to store observed values for chi-squared tests.
What is the matrix?
These words tells you to "narrow your scope" or "change your denominator" in conditional probability questions.
What is "given that"?
If a population of deer increases by 5% each year, what is my common ratio for the geometric series?
What is 1.05? (1 + .05)
You solve for the x-intercepts (roots) of a quadratic using this app on the calculator.
What is PLYSMLT 2 -> Roots of Polynomial?
This is the total area of the faces of a 3-dimensional sold.
What is the surface area?
If you have grouped data, you have to find this within the x groupings to enter into the GDC in L1.
What is the mid-interval value?
