MATH REVIEW AND CALCULATOR FUNDAMENTALS ac 255 CALCULATOR FUNDAMENTALS The basic operation of the calculator and the priority it assigns to each mathematical operation wewe covered in detail in Experiment de 1. In this section, we concentrate on its use witb complex numbers. Basic Operations First let us examine the basic operations associated with some of the equations introduced in the first part of this laboratory exercise. Pythagorean Theorem: Because the priority list requires that the squaring operation be pecformed before the addition between factors, the operations can be entered just as they appear. That is, for z248 the following is entered using T1-89 calculator However, if the operation to be performed is z -V4 then the addition must be perforimed before the square root, requiring the use of the brackets: Trignometric Functions All operations such as cosor an must be entered as to be sure the division is performed before the inverse operation For enter the following for the T1-89 calculator: antan 2ND | MATH | ↓ | A ↓ Trig |-| ↓ | 9 ↓ tan ( | ENTER 3 | | ÷ | 8 | | ) | | ENTER)-> 20.56"
