$\sqrt{2 \\ }$

Answer 2

Answer:

Very important basic trigonometry values

$\begin{tabular}{| c | c | c | c | c | c |}\cline{ 1-6 }\multicolumn{6}{| c |}{Trigonometric Values} \\\cline{ 1-6}Angle&0^{\circ}&30^{\circ}&45^{\circ}&60^{\circ}&90^{\circ}\\\cline{ 1-6 } sin\theta & 0 & 1/2 & 1/\sqrt{2} & 3/\sqrt{2} & 1\\cos\theta & 1 & \sqrt{3}/2 & 1 & 1/2 & 0\\tan\theta & 0 & 1/\sqrt{3} & 1 & \sqrt{3} & nd\\cot\theta& nd & \sqrt{3} & 1 & 1/\sqrt{3} & 0\\sec\theta & 1 & 2/\sqrt{3} & \sqrt{2} & 2 & nd\\cosec\theta & nd & 2 & \sqrt{2} & 2/\sqrt{3} & 1\\\cline{1-6} \end{tabular}$

Thanks!
