Quadratic Explorer functions

SOLVE

Solve quadratic. Given the coefficients of a quadratic

 

equation ax2+bx+c=0, returns the real solutions.

 

SOLVE(a, b, c)

 

Example:

 

SOLVE(1,0,-4) returns {-2, 2}

DELTA

Discriminant. Given the coefficients of a quadratic equation

 

ax2+bx+c=0, returns the value of the discriminant in the

 

Quadratic Formula.

 

DELTA(a, b, c)

 

Example:

 

DELTA(1,0,-4) returns 16

Common app functions

In addition to the app functions specific to each app, there are three functions common to the following apps. These use as an argument an integer from 0 to 9, which corresponds to one of the Symbolic view variables for that app.

 

Function (F0–F9)

 

Solve (E0–E9)

 

Statistics 1Var (H1–H5)

 

Statistics 2Var (S1–S5)

 

Parametric (X0/Y0–X9/Y9)

 

Polar (R0–R9)

 

Sequence (U0–U9)

 

Advanced Graphing (V0–V9)

CHECK

Check. Checks—that is, selects—the Symbolic view variable

 

corresponding to Digit. Used primarily in programming to

 

activate Symbolic view definitions in apps.

CHECK(Digit)
