Question 11. Candidates who are studying in Class 12 can also check Class 12 NCERT Solutions from here. (x x1) (x x1) + (y y1) (y y2) + (z z1) (z z2) = 0. (iii) If 1, m, n are direction cosines of a vector r and a b, c are three numbers, such that l / a = m / b = n / c. Then, we say that the direction ratio of r are proportional to a, b, c. l = a / a2 + b2 + c2, m = b / a2 + b2 + c2, n = c / a2 + b2 + c2, (iv) If is the angle between two lines having direction cosines l1, m1, n1 and 12, m2, n2, then, (a) Lines are parallel, if l1 / 12 = m1 / m2 = n1 / n2, (b) Lines are perpendicular, if l112 + m1m2 + n1n2, (v) If is the angle between two lines whose direction ratios are proportional to a1, b1, c1 and a2, b2, c2 respectively, then the angle between them is given by, cos = a1a2 + b1b2 + c1c2 / a21 + b21 + c21 a22 + b22 + c22, Lines are parallel, if a1 / a2 = b1 / b2 = c1 / c2. https://www.padslakecounty.org/wp-content/uploads/rekomendasi-situs-slot-gacor-gampang-menang/, https://orbitatechnology.com.co/wp-includes/slot-gacor/, https://threeguru.com/wp-content/uploads/situs-slot-gacor-gampang-menang/, https://consultarsaldodetarjetavisavalealimentos.com.ar/daftar-situs-slot-gacor-gampang-menang/, https://www.ippoedixon.com/wp-content/uploads/sg/, https://ihealzy.com/wp-includes/slot-gacor/, https://tribunadovale.com.br/wp-includes/slot-gacor/, https://triviatodayanswers.com/wp-includes/slot-gacor/, https://kokoss.ro/wp-includes/slot-gacor/, https://threeguru.com/wp-content/uploads/slot-bonus-new-member/, https://quotestube.com/wp-includes/bocoran-situs-slot-gacor/, https://citi.edu.mn/wp-includes/link-slot-gacor-terbaru, https://www.jojoboutique.co.uk/wp-includes/slot-gacor/, https://jadasluxurybeautysupply.com/wp-includes/sbobet/, https://imarketshop.ro/wp-content/uploads/bocoran-slot-gacor/, https://dalatopnews.com/wp-includes/slot-gacor/, https://almanhaperfumes.com/wp-includes/sbobet/, https://thpttranhungdaohoian.edu.vn/modules/news/slot-gacor/, https://active-languages.com/wp-includes/slot-gacor/, https://care-national.com/wp-includes/slot-gacor/, https://universalremotescode.com/slot-gacor/, https://nextgenbioproducts.com/wp-includes/slot-gacor/, https://ihealzy.com/wp-content/uploads/2022/sbobet/, https://sodamndelish.com/wp-includes/link-slot-gacor/, https://ijamvirtual.edu.pe/wp-includes/sbobet-online/, https://babel-jo.com/wp-content/languages/slot-gacor/, https://www.koldacommunication.com/wp-includes/slot-bonus/, Download Indias Leading JEE | NEET | Class 8-10 Exam preparation app, Get Lectures, Study Material, Tests, Notes, PYQ, Revision & more on, 3D Geometry Class 12 Notes for IIT JEE and Boards, Application of Integrals Class 12 Notes for IIT JEE, JEE Main Previous Year Questions Topicwise, Tham gia W88 Slot Playtech c c hi nhn thng ln ti 480,494,000 VND.
