Sin numbers and mark averages

This week we continued to concentrate on loops and how they work. On Monday, we started a program where the user inputs a sin number and the program performs a certain calculation that indicates if the sin number is valid or not. On Tuesday, we continued to work on our sin assignments and our computer science teacher started marking on a voluntary basis. On Wednesday we did an assignment that was for fun and for our own interest and not for marks. It was very hard and complicated and required lots of new variable types that I have never used before. On Thursday the teacher was absent and we did an assignment on computer history, and important definitions and terms. Today we did a while loop program, where the user inputs numbers into an input box and types -1 when they want to stop. The program outputs the average the highest mark and the lowest mark.

Throughout the week i still had to get help ocasionally from people and i continue to try and figure out things on my own. My goal is to continue to try until i can do all my programs without any assitance. Today working on the Average mark assignment i had everything right except for about 4 lines so i'm gettin close.
