Racket Assignment - Help Finding Error

[xoxoxoxoxo]

I'm attempting to write a program in Racket that will consume 4 points p1, p2, p3, and p and produce the value true iff p is on or within the triangle formed by p1, p2, and p3. The program will do this by taking the cross-products p1p2 x p1p, p2p3 x p2p, and p3p1 x p3p, and produce the value true if the resulting vectors point in the same direction. I submitted the program to Marmoset, but it failed two of the public tests, and I have no idea why. I have continuously tried the check-expect test, but the results are all correct.
Are there any other test suites I can write in Racket that will help me find the error in my program?

Have you considered all edge cases?

There is many people that can help at university if you have an issue; however this is an assignment. The point of this assignment is for you to understand Racket as well as understand the cases. Do more unit testing before you submit and start assignments early.

I'm guessing you're in CS 145?

i guess this is a cs135's question. I think i was working on this question when i was in cs135

this was a CS145 Question in September. Would be surprised to see 135 doing it so early
