Two finite sets have m and n elements. The total number of subsets of the first set is 112 more than the total number of subsets of the second set. Find the valuesof m and n.

an equilateral triangle is inscribed in the parabola y^{2}=4ax,where one vertex is at the vertex of the parabola.find the length of the side of the triangle.pls answer me as soon as possible.

Prove that:

4 cosA cos(60-A) cos(60+A) = cos3A

Prove that sin3x + sin 2x – sinx = 4 sinx cos x/2 cos3x/2

sir, can u explain me how to find tan inverse in log books..
