Sir, here why is the triangle considered to be equilateral, is there any reason behind this, or how do we make such assumptions, plz help me sir??
Hi,
Please rephrase your question . Also, upload the figure, if there is any, accompanying the question.
Regards
In a triangle ABC , find the least value of,
cot A/2 * cot B/2 * cot C/2 * cos A/2 * cos B/2 * cos C/2
In these types of questions , we consider the simplest cases available to us.
Also we use the fact that the given expression is symmetric with respect to the three angles
Which gives us the simplest case of Equilateral Triangles
