Question3 : We have a triangular pyramid OABC in R defined by points O (origin), A(1, 3, –1), B(2,1, –2) and С(3, —2,4). (3a) Find the angle between vector OA and the plane passing through points A, B, C. (3b) Let N be the mid point between A and B. Find the distance from N to the plane passing through points O, A and C. (3c) Let L1 be the line passing through points A and B. Let L be the line passing through points O and C. Write down parametric equations for these lines and find the distance between them.
