Tutorial exercise #9

Hi, I noticed that I did not write much about this week’s tutorial exercise (#9). So although it has already past, I thought I should give my impression of this week’s tutorial and also the quiz.

Starting off with koch.rkt, there are two primary functions within this program. Firstly, the koch itself which uses the input given (which is a number) and displays an output of a line or multiple lines. It will just output a normal horizontal line, but as you increase your number value as input, it will rotate 60 degrees then rotate -60 degrees from the last position to make a triangular shape (with no bottom) like ‘^’.  It will continually add as you increase the number. Thus in the next function, the koch-snowflake, it takes these individual koch’s and puts them together. Which will ultimately create and snowflake shape if the value for input is high enough. Next program is spiral.rkt. This program seems to have the same intuitive concept as koch.rkt where the user inputs a number and depending on that value, it will display an output of spiral lines. Overall, the two programs were not very complicated once one is able to wrap their head around it. The quiz consisted of 5 questions which were all related to the functions mentioned above, I am not sure if I got them all right but the questions were very fair considering that the questions were directly from the program we studied during the tutorial.

I hope everyone did well on the quizzes and project #2!
