Find the shortest distance between lines vector r =6i+2j+2k+λ (i-2j+2k) and vector r=4i-k+μ(3i-2j-2k) and asked Jan 25, 2018 in Mathematics by sforrest072 ( 128k points) three dimensional geometry A norma vector to the rst plane h1;2;3iand The cosine of the angle between the lines Also for r —7i —6k +g(i 2j 2k), b Angle between the lines is same as the angle between the vectors parallel to the respective lines. Take the coordinates of two points you want to find the distance between. (6 Points) Find a vector parallel to the line of intersection for the two planes x+ 2y+ 3z= 0 and x 3y+ 2z= 0: Solution: A vector which gives the direction of the line of intersection of these planes is perpendicular to normal vectors to the planes. Magnitude of (𝑏1) ⃗ × (𝑏2) ⃗ = √(8^2+0^2+〖(−4)〗^2 ) = 𝑖 ̂ [ 12−4] − 𝑗 ̂ [6−6] + 𝑘 ̂ [2−6] |(𝒃𝟏) ⃗ × (𝒃𝟐) ⃗ | = √(64+16) = √80 = 4√5 (2𝑖 ̂ − 4𝑗 ̂ + 4𝑘 ̂) Take any point on the first plane, say, P = (4, 0, 0). The trick here is to reduce it to the distance from a point to a plane. Solution: [a] a 1 = i – 2j + 3k So, Point of intersection is (−1, −6, −12). The shortest distance between two parallel lines is equal to determining how far apart lines are. (i) Find the angle between them. He has been teaching from the past 9 years. To find the angle between two lines: cosθ= u d •u D Distance from a point to a line: d P P d d P l × ( , ) = 0 1 10) Find the distance from P(2, 0, 2) to the line through P 0(3, -1, 1) parallel to i - 2j - 2k. And, asked Oct 28, 2020 in Mathematics by Eihaa ( 50.5k points) To find a step-by-step solution for the distance between two lines. = 2𝒊 ̂ − 4𝒋 ̂ + 4𝒌 ̂ … Find the shortest distance between the lines r = i+2j+3k + lambda (2i+3j+4k) and r = 2i+4j+5k+t(3i+4j+5k) 1 See answer dukisyrti6570 is waiting for your help. 𝑟 ⃗ = −𝑖 ̂ − 6𝑗 ̂ − 12𝑘 ̂ to Now, Thus, (March – 2011) Answer: Question 2. So let's think about it for a little bit. Find the angle between the lines r=3i+2j-4k+ λ(i+2j+2k) and r=5i-2k+μ(3i+2j+6k) Maharashtra State Board HSC Arts 12th Board Exam.
