Stats:

SD = calculations involving standard deviation

REG = calculations involving regression

E.g., [cont.]

i) Write the function f(x) = ... into your calculator [use alpha then X for the variable]

ii) = lower bound

iii) = upper bound

iv) = incremental steps.

Well, if you want to check if a statement such as "2 + 4 > 7" is true or false simply do the following:

2 + 4

SHIFT (choose VERIFY)

choose >

7

Calculator displays FALSE

[cont]

Use linear regression!

E.g., between (2,2) and (3,5)

MODE -> REG -> Lin

2,2 DT

3,5 DT

S-VAR

A = -4

S-VAR

B = 3

Hence equation of the line is y = A + Bx i.e., y = -4 + 3x

I collect maths materials (exams, questions, textbooks) from around the world - if anyone wants to donate some feel free to comment/message :)
