Function table (2 variables) Calculator

Calculates the table of the specified function with two variables specified as variable data table.

f(x,y) is inputed as "expression". (ex. x^2*y+x*y^2 )
The reserved functions are located in "Function List".

    Radio announcers must time their speeches so that commercials and news updates are the correct length. Do you know how fast you talk? How fast your friends talk? Students wrote the tongue twisters like the ones below to use in an experiment. Each tongue twister is made up of a different number of words. For each tongue twister, the students timed how long each person took to say it. Then they calculated the average time.

    • Cheyenne shares pseudo sonar noise codes. (6 words)
    • The sunshade sheltered Sawyer from the sunshine. (7 words)
    • Parker picked a plentitude of perfect Paradise pears. (8 words)

    The results of the students’ experiment are shown in the table

    Linear Algebra student reviewing an old algebra property, generating two tables of results to compare (I should've used the two functions calculator instead). I was checking that vector addition is preserved for a transformation, to prove linearity, when I made an error like: 2 |u+v| = 2|u| + 2 |v|. I should have divided out the constant to reveal that this is |x+y| = |x| + |y| , which I know is false. But tediously crafting a 5x5 table with x and y axes for {-2,2} was fun in a weird nerdy way.

    In conclusion: all transformations containing the absolute value of a variable are nonlinear because vector addition is not preserved. Thanks for the service. I used to make test cases like this all the time in high school algebra. It's cool because you don't need to take someone's word for it, which is important when your question is too obscure or specific to easily find an answer to.
