The “piecewise” function returns one value when an expression is true, and another value

when the expression is false.

The syntax of the “piecewise” function is shown below.

piecewise(<condition expression>, <return value when true>, <return value when false or

indeterminate>[ ) ]

piecewise(<condition expression>, <return value when true>, <return value when false>,

<return value when indeterminate>[ ) ]

Problem

Use this keyboard:

Operation

mth abc cat 2D

For the expression Func [piecewise] 0 X, 1,

0 < x (x = variable), return 1 2 , 0 w

when x is greater than 0,

2 when x is 0 or less, and 0

when x is undefined.

k Angle Symbol (∠)

Use this symbol to specify the coordinate format required by an angle in a vector.

You can use this symbol for a vector only.

Problem

Use this keyboard:

Operation

mth abc cat 2D

Convert the polar OPTN Func Change the [Angle] setting to

coordinates r = 2, “Radian”.

= π /4 to rectangular [toRect] [9 2 ),

coordinates. [1, 1] 7/ 4 )]w

k Derivative Symbol (’)

A single derivative symbol indicates the first derivative of an equation in the format:

<variable name>’.

Problem

Use this keyboard:

Operation
