คำอธิบาย The Physics of Vectors

This is an app which will help the user do most calculations of basic physics and math vectors. There are three separate screens. One is for single vector calculations (scalar multiplication of a vector, magnitude and direction of a vector); another one is for simple two vector calculations (addition, subtraction and angle between 2 vectors); the final screen is for more complex vector calculations (dot and cross products).
Vectors are input by inserting the x and y components separated by ONLY a comma. For example, 3,4 or 1,3. If any other characters/text/dimensions are added, the app will crash. DO NOT DO IT.
This app expects that you know about something about vectors. The app was created mainly because my high school will not teach vectors to physics classes next year; students will have to learn it themselves over the summer and in the precalculus curriculum.
