Question

ifA=pie/3 then find the value of sinA-cosA

Answer 1

A = pi/3 = pi/3 / 180/pi = 60 degrees

Therefore,

                     sinA - cosA = sin60 - cos60 = root of 3 - 1 / 2

Answer 2

A = $\frac{\pi}{3}$

$\frac{\pi}{3} = 60^o$

$Sin \frac{\pi}{3} - Cos \frac{\pi}{3} = Sin60^o - Cos60^o$

$\frac{ \sqrt{3} }{2} - \frac{1}{2}$

$\frac{ \sqrt{3}-1 }{2}$
