Quadratic Explorer functions

SOLVE Solve quadratic. Given the coefficients of a quadratic

equation ax

+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

+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)

Example:

With the Function app as the current app, CHECK(1) checks

the Function app Symbolic view variable F1. The result is that
