3-182 Full Command and Function Reference
The polynomial is calculated at the point global = 0. The expression symb may have a removable
singularity at 0. The order, n, is the relative order of the Taylor polynomial–the difference in order
between the largest and smallest power of global in the polynomial.
TAYLR always returns a symbolic result, regardless of the state of the Numeric Results flag (–3).

TCHEBYCHEFF
CAS: Return the nth Tchebycheff polynomial.
TCOLLECT
CAS: Linearize products in trig expression by collecting and combining sine and cosine terms.
TDELTA
Type: Function
Description: Temperature Delta Function: Calculates a temperature change.
TDELTA subtracts two points on a temperature scale, yielding a temperature increment (not an
actual temperature). x or x_unit1 is the final temperature, and y or y_unit2 is the initial
temperature. If unit objects are given, the increment is returned as a unit object with the same
units as x_unit1. If real numbers are given, the increment is returned as a real number.
