Zamień kąt 120° na radiany, a kąt pi/3 radianów na stopnie

360°=2π [rad] //:3 120°=2π/3 [rad] 120°=(2/3)π [rad] 360°=2π [rad] //:2 180°=π [rad] //:3 60°=π/3 [rad] π/3 [rad]=60°

Stopnie na radiany: [latex]alpha[rad] = alpha[^o}] * frac{pi}{180^{o}}\\120^{o} = 120^{o} * frac{ pi} {180} rad = frac{2 pi }{3} rad[/latex] Radiany na stopnie: [latex]alpha[^{o}] = alpha[rad]*frac{180^{o}}{pi} }[/latex] [latex]frac{ pi }{3} rad = frac{ pi }{3}*frac{180^{o}}{ pi } = 60^o}[/latex]
