am trying to prove the this trig question but i have been unsucessful.
Tan A+ Cot A = 2Cosec 2A
Hi sigma1,
$\displaystyle tanA+cotA=\frac{sinA}{cosA}+\frac{cosA}{sinA}=\fra c{sinA}{sinA}\frac{sinA}{cosA}+\frac{cosA}{cosA}\f rac{cosA}{sinA}$
$\displaystyle =\frac{sin^2A+cos^2A}{sinAcosA}=\frac{1}{sinAcosA} =\frac{1}{\frac{1}{2}sin2A}$
$\displaystyle =\frac{2}{sin2A}=2cosec2A$
