H2 Maths 3.3 - Planes: Equations, Angles, and Distances
Overview
Transcript
What you will learn
Plane through A(1,0,2), B(3,-1,4), C(2,2,0); find Cartesian equation, angle with line l, and distance from P(4,1,-1).
Normal n = AB x AC = (-2, 6, 5); Cartesian equation -2 x + 6 y + 5 z = 8.
Angle between line and plane: sin theta = |d . n| / (|d| |n|) = 10 / sqrt(1365); theta about 15.7 degrees.
