Mathematica Triangle Functions for Mathematical Analysis - Get Feedback Now!

AI Thread Summary
The discussion revolves around the evaluation of mathematical functions related to triangle area calculations, particularly using Heron's Formula. A user shares a link to their work and seeks feedback. It is noted that the area for a triangle with sides 3, 1, and 2 is zero due to the semiperimeter being equal to one of the sides, which leads to a zero term in the formula. This is further emphasized by the observation that such a triangle cannot exist geometrically, as the height would also be zero. The conversation highlights the importance of understanding the underlying mathematical principles and acknowledges the potential confusion when working late.

Seem to work. Although could just state the elementary formulae used. Having said that, it depends upon the audience.
 
most people wouldn't know how to use the formula if i state it...
 
i tried the first method


the area for triangle 3,1,2 is 0 square units
 
because the semiperimeter is 3, thus when you apply it to Heron's Formula it has a 0 term in the squareroot, since it's all multiplication, any term multiply by 0 would produce 0. Thus my functions works fine.
 
Or for a more "obvious" reason, if you try to draw a 3-1-2 triangle, you'll find its height is 0.

As it has to be as 2+1 = 3.
 
oops, silly me. it was late and my brain wasnt working very well
