प्रश्न संख्या 1 से 6 तक प्रत्येक प्रश्न 1 अंक का है ।
Question numbers 1 to 6 carry 1 mark each. 1
- सदिश <math>\overrightarrow{a} = \hat{i} - 2\hat{j}</math> की दिशा में एक सदिश ज्ञात कीजिए जिसका परिमाण 7 इकाई है । Find a Vector in the direction of <math>\vec{a} = \hat{i} - 2\hat{j}</math> that has magnitude 7 units.
- यदि <math>\overrightarrow{a}</math> तथा <math>\overrightarrow{b}</math> मात्रक सिदश हैं, तो <math>\overrightarrow{a}</math> तथा <math>\overrightarrow{b}</math> के बीच का कोण क्या है, जबिक <math>\sqrt{2}\overrightarrow{a} - \overrightarrow{b}</math> एक मात्रक सदिश है ?
1 If <math>\overrightarrow{a}</math> and <math>\overrightarrow{b}</math> are unit Vectors, then what is the angle between <math>\overrightarrow{a}</math> and <math>\overrightarrow{b}</math> so that <math>\sqrt{2}\overrightarrow{a} - \overrightarrow{b}</math> is a unit vector?
- यदि एक रेखा निर्देशांक अक्षों की धनात्मक दिशाओं के साथ कोण <math>\alpha</math>, <math>\beta</math>, <math>\gamma</math> बनाती है, तो <math>\sin^2\alpha + \sin^2\beta +</math> <math>\sin^2\gamma</math> का मान लिखिए ।
1 If a line makes angles <math>\alpha</math>, <math>\beta</math>, <math>\gamma</math> with the positive direction of coordinate axes, then write the value of <math>\sin^2\alpha + \sin^2\beta + \sin^2\gamma</math>.
- यदि <math>A = \begin{pmatrix} 1 & 2 \\ 3 & -1 \end{pmatrix}</math>, <math>B = \begin{pmatrix} 1 & 3 \\ -1 & 1 \end{pmatrix}</math> हैं, तो <math>|AB|</math> का मान लिखिए ।
