Detailed Solution
Download Solution PDFअवधारणा:
यदि एक रेखा के दिशा अनुपात (l, m, n) हैं तो इसके दिशा कोसाइन
\(\displaystyle\rm\left({l\over\sqrt{l^2+m^2+n^2}},{m\over\sqrt{l^2+m^2+n^2}},{n\over\sqrt{l^2+m^2+n^2}}\right)\) हैं।
गणना:
दिशा अनुपातों से दिशा कोसाइन के सूत्र का उपयोग करते हुए आवश्यक दिशा कोसाइन हैं:
\(\displaystyle\rm\left({1\over\sqrt{1^2+(-3)^2+2^2}},{-3\over\sqrt{1^2+(-3)^2+2^2}},{2\over\sqrt{1^2+(-3)^2+2^2}}\right)\)
= \(\displaystyle\rm\left({1\over\sqrt{14}},{-3\over\sqrt{14}},{2\over\sqrt{14}}\right)\)
