# Intro to Mathematica - La Salle University

Intro to Mathematica Wolfram Mathematica An important feature of Mathematica is its ability to manipulate symbols

It also allows for numerical solutions and data visualization. Start/All Programs/Wolfram Mathematica 11.1.1/Wolfram Mathematica 11.1.1

Click on New Document Use Shift+Enter to distinguish something to be evaluated versus

just explanatory text vf == vi + a t In Mathematica and equation requires two equal signs. The expression a t means a multiplied by t and can also be written as

a*t. Without a space at would be a new symbol. The symbol vf stands for the final velocity The symbol vi stands for the initial velocity The symbol a stands for the acceleration which is constant for this scenario

The symbol t stands for time Save it! Mathematica can solve

(symbolically) the equation for the variable t. Enter the second kinematics equation

Use /. (ReplaceAll) to substitute in the first kinematics equation solved for time into the second kinematics equation

Using Expand Assign values to symbols to determine a numerical solution If the acceleration is -9.8 m/s^2

And the initial velocity is 15m/s and initial height is zero What is the final position when the final velocity is 0 (i.e. the highest height)?
