DIVIDE

Divide two or more numeric arrays, matrices, dataframes, or constants element-wise. When a constant is divided into an array or matrix, each element in the array or matrix will be divided by the constant value. Params: a : OrderedPair|Scalar|Vector The input that will be divided by b. b : OrderedPair|Scalar|Vector The input that will divide a. Returns: out : OrderedPair|Scalar|Vector OrderedPair if a is an OrderedPair. x: the x-axis of input a. y: the result of the division of input a by input b. Scalar if a is a Scalar. c: the result of the division of input a by input b. Vector if a is a Vector. v: the result of the division of input a by input b.

In this example we use DIVIDE to undo the effects of a SINE node.

We first generate two sine functions using LINSPACE and SINE nodes, and then use DIVIDE node to cancel them out which generates a flat scatter plot in SCATTER node.
