Subtraction - Vector arithmetic
Computationally, subtraction is very similar. Given the vectors a→= (a1, a2, a3) and b→ = (b1, b2, b3) the difference of the two vectors is given by,
a→ - b→ = (a1 - b1 , a2 - b2 , a3 - b3)
Now here is the geometric interpretation of the difference of two vectors.
what is the product of the solutions to the equation: x2+4x=-4
Volumes for Solid of Revolution Before deriving the formula for it we must probably first describe just what a solid of revolution is. To find a solid of revolution we start o
how do you find the co=efficent when there are two brackets involved?
Determine or find out the direction cosines and direction angles for a = (2, 1, -4) Solution We will require the magnitude of the vector. ||a|| = √ (4+1+16) = √ (21)
Evaluate following. √16 and Solution To evaluate these first we will convert them to exponent form and then evaluate that since we already know how to
If two vertices of an equilateral triangle are (0, 0) and (3, 0), find the third vertex. [Ans: 3/2 , 3/√ 3/2 or 3/2, -3√ 3/2] Ans: OA = OB = AB OA 2 = OB 2 = AB 2
r=asin3x
The midpoint of the line joining (2a, 4) and (-2, 3b) is (1, 2a +1).Find the values of a & b. (Ans: a = 2, b = 2) Ans : A(2a, 4) P(1, 2a + 1) B(-2,
