Homework Help Overview

The discussion revolves around finding the area of a triangle with given side lengths a, b, and c, without using established formulas like Heron's Formula. Participants are exploring alternative methods to derive the area conceptually and mathematically.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants suggest various methods, including splitting the triangle into right triangles and using integration. There is a discussion about the challenges of setting up the triangle for integration given only the side lengths.

Discussion Status

The conversation is ongoing, with participants offering different approaches and questioning the feasibility of each method. There is no explicit consensus, but several lines of reasoning are being explored.

Contextual Notes

Participants are working under the constraint of not using known formulas for area calculation, which raises questions about how to define the triangle's dimensions and limits for integration.

How can I go about finding the area of a triangle with sides a, b, and c, assuming we do not already know a formula for it (such as Heron's Formula)? Kind of like a proof, I suppose.

You could split it into 2 right angle triangles. It's failry easy to calculate the area of a right angle triangle.

I take it you mean set the triangle up so that one vertex is at the origin and another is along the positive x-axis. The difficulty with that is that, since you know only the lengths of the sides, you would have to break it into right triangles to determine the limits of integration. Once you have done that, it is simpler to find the area of the right triangles, mgb_phys' recomendation, than to integrate.
