Hello,
I thought you might be able to help me.
In spring I will take exams which include quick thinking tasks from maths. So is there any way of how to improve these skills or I have got nothing to do with them, because they are just imborn? Do the genes in this field take a big part or nothing i should worry about if i study properly?

Can someoneone help me to explain how to do it by given the complete solution.

1) Find a unit vector that is orthogonal to a and b where
a = 9 i - j - 2 k and b = -5 i + 2 j - 7 k .

2) Consider the line passing through the point P, whose position vector is -5 i + 10 j, and parallel to the vector -3 i - 4 j. Find a cartesian equation for the line.

3) Find the position vector of the point of intersection of lines L1, L2 with vector equations intersecting, where
L1: r = -2 i - 5 j + s (7 i + j)
L2: r = -4 i + 10 j + t (- i - 7 j)

People consider those good at math to be clever people, but my challenge will find out if this is true. Teach me some complicated looking mathmatical art and if I can understand it, you get 10 points and a big thank you from this dunce.

What is "e"? What does e stand for, what equations can it be used in? And what fields use it, what applications does it have? Just wondering. i know I've heard of e, but I have no idea what it is used for.

Hey, I'm doing some algebra stuff, but I don't know how to do what I'm working on. Here's some examples of what I'm dealing with:

(2a - 3)/6 = (4a)/3 + 2/3

(3x)/5 + 3/4 = (6x)/10

(2b - 3)/7 - b/2 = (b + 3)/14

Could anyone tell me how to solve these problems and others like them?
