Cos(x)=sin(x). Then the value of cos^4x + sin^4x=?

If sin(a)/sin(b) = p and cos(a)/cos(b) = q then tan(b) =?

[cot(a)cosec(a)+1]/[cot(a)+cosec(a)1]=?

Prove #(cotAcosecA+1)/(cotA+cosecA1)=cosecA cotA#?

ABCD is a square. The diagonals AC & BD cut at A. From B a perpendicular is drawn to the bisector /_DCA and it cuts AC at P and DC at Q. Can you prove that DQ = 2PE?
