If P=Sin A.Sin B, Q= Sin C.Cos A, R = Sin A.Cos B and S=Cos A.Cos C then 5(P^2+Q^2+R^2+S^2) = ??

We can see that

P^2 + R^2 = {sin(A)}^2 and Q^2 + S^2 = {Cos(A)}^2

adding we get P^2 + R^2 + Q^2 + S^2 = 1

So 5(P^2 + R^2 + Q^2 + S^2) = 5

If Sin A + Cos A = sqrt(2) Sin (90 - A) then Cot A = ??

If in a triangle ABC: Cos A + Cos B + Cos C = 3/2 then what is so special about this triangle?
