Question about Texas Instruments TI-15 Explorer Calculator

I am locked in the fix function. All of the mathematical equations that I perform are being rounded. I want the answers to be exact. How can I get out of the fix function

You can either use the slash key / or if you are using Word you can insert am equation

At the top of Word click the insert button, third from the left.

Then on the far right click insert equation. There you have an option to put in almost any mathematical symbol. You could use either the division or fraction sign.

There are various ways that a mathematical expression fails to be an equation. It lacks a relational operator (symbol). It has a less than sign, or a greater than sign, or a combination of other symbols. If you language homework requires(?) that you find an antonym for equation, try non-equation.

What one does to one side of the equation must be done to the other.

Starting with m=t-r, add r to both sides:

m+r = t-r+r or m+r=t. Subtract m from both sides:

m+r-m=t-m or m-m+r= t-m or**r=t-m**

Starting with m=t-r, add r to both sides:

m+r = t-r+r or m+r=t. Subtract m from both sides:

m+r-m=t-m or m-m+r= t-m or

You cannot solve the quadratic equation with this calculator. It does not have a solve program.

However if you wnat to create a table of values for a function (any type of function that uses the basic scientific function keys ) you use the TABLE Computational Mode.

You press MODE

You select TABLE

You enter a mathematical expression 3X^2-.33X+ 15

You generate the table of values.

Definition

A mathematical statement used to evaluate a value. An equation can use any combination of mathematical operations, including addition, subtraction, division, or multiplication. An equation can be already established due to the properties of numbers (2 + 2 = 4), or can be filled solely with variables which can be replaced with numerical values to get a resulting value. For example, the equation to calculate return on sales is: Net income ÷ Sales revenue = Return on Sales. When the values for net income and sales revenue are plugged into the equation, you are able to calculate the value of return on sales.

There are many types of mathematical equations.

1. Linear Equations y= mx + b (standard form of linear equation)

2. Quadratic Equations y= ax^2+bx+c

3. Exponential Equations y= ab^x

4. Cubic Equations y=ax^3+ bx^2+cx+d

5. Quartic Equations y= ax^4+ bx^3+ cx^2+ dx+ e

6. Equation of a circle (x-h)^2+(y-k)^2= r^2

7. Constant equation y= 9 (basically y has to equal a number for it to be a constant equation).

8. Proportional equations y=kx; y= k/x, etc.

The [MODE] key can be used to select the modes described below.

Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes

Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetric calculations

(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

SD: Single-variable statistical calculations

(sample standard deviation, etc.)

LR or REG: Paired-variable statistical calculations

(linear regression statistical calculations, etc.)

BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations

MAT: Matrix calculations (determinants, etc.)

VCT: Vector calculations

EQU: nth degree equations, simultaneous equations

2) Display Settings

Use these settings to control how calculation results are displayed.

Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

3) Angle Unit Setting

(90°=?/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads

4) Engineering Mode

Use this mode when you want to input and perform calculations using engineering symbols.

What you need is a software that can perform what is called "symbolic calculus". For example to give you the answer on how looks the solution for the 2 grade equation a*x^2+b*x+c=0. There are two main software packages that can perform this: Maple (http://www.maplesoft.com) and Mathematica (http://www.wolfram.com).
