1.4: Equations of Planes in 3d - Mathematics LibreTexts
WebEach unit vector is perpendicular to one of the three mutually perpendicular surfaces and oriented in that direction in which the coordinate increases. The unit vector ar is directed radially outward, normal to the sphere r = constant, and lies in the cone θ = constant and the plane φ = constant. WebWhen two planes are perpendicular, the dot product of their normal vectors is 0. Hence, 4a-2=0 \implies a = \frac {1} {2}. \ _ \square 4a−2 = 0 a = 21. . What is the equation of the plane which passes through point A= (2,1,3) A … WebEngineering Mechanical Engineering 2.
