Q. CH 1342Final Exam, Fall 2023Find a standard equation for the plane containing the line L(t)=(−4,0,6)+t(3,5,1) and the point (2,1,3)
Identify Point on Line: Identify a point on the line L(t) by setting t=0.Point on the line: (−4,0,6).
Find Direction Vector: Find the direction vector of the line L(t) which is also a vector parallel to the plane.Direction vector: (3,5,1).
Find Connecting Vector: Find the vector connecting the point on the line to the given point (2,1,3).Connecting vector: (2−(−4),1−0,3−6)=(6,1,−3).
Calculate Normal Vector: Calculate the normal vector of the plane by taking the cross product of the direction vector and the connecting vector.Normal vector: (5∗(−3)−1∗1,1∗3−(−4)∗(−3),(−4)∗1−6∗3)=(−15−1,3−12,−4−18).
Simplify Normal Vector: Simplify the normal vector.Normal vector: (−16,−9,−22).
Write Plane Equation: Use the normal vector and the point on the line to write the standard equation of the plane.Equation: −16(x+4)−9(y−0)−22(z−6)=0.
Expand Equation: Expand and simplify the equation of the plane.Equation: −16x−64−9y−22z+132=0.
Combine Like Terms: Combine like terms to get the final standard equation of the plane.Equation: −16x−9y−22z+68=0.
