Question

Utilizind tabelul trigonometric,ordonati crescator numerele:
a)1,sin45°,sin30°,0,sin60°;Ajutatima va rog!

Answer 1

 

$\displaystyle\bf\\\textbf{Consideram ca suntem in cadranul 1}\\\\sin\,45^o=\frac{\sqrt{2}}{2} \\\\sin\,30^o=\frac{1}{2}\\\\ sin\,60^o=\frac{\sqrt{3}}{2}\\\\0<\frac{1}{2}<\frac{\sqrt{2}}{2}<\frac{\sqrt{3}}{2}<1\\\\Rezulta:\\\\0<sin\,30^o<sin\,45^o<sin\,60^o<1\\\\\textbf{Le scrierem ordonat crescator:}\\\\\boxed{\bf0;~sin\,30^o;~sin\,45^o;~sin\,60^o;~1}$
