We can use the knowledge about concept of parallel line related to the topic vector
especially in addition and subtraction of vector.
Addition of vector
The vector is the resultant of the vector and is represented mathematically as . Note that the vector has the same direction and The example above for the addition of vector that is parallel.There are many example that can relate the concept parallel line to addition and subtraction of vector.
Multiplication algebraic involving denominator with one term
For example : Find
WHAT IS THE RELATIONSHIP BETWEEN
ALGEBRAIC EXPRESSION AND VECTOR???
Multiply algebraic expression with numerator We use algebraic expression to solve problems especially in addition and subtraction vector. Obviously, it use algebraic expression when to express any vector in any term such as in terms of and
Expand and multiply two algebraic terms with fraction Thus, as we can see from the example above subtopic addition and subtraction of vector is connected to the algebraic expression as we always use to solve problem relate to vector
The straight line is a line that does not curve. In geometry a line is always
a straight (no curve).
In coordinate geometry, lines in a Cartesian plane can be described algebraically by linear equations and linear functions. In two dimensions, the characteristic equation is often given by the slope-intercept form:
The concept of straight line is used in the topic vector.
WHY???....BECAUSE vector also is a straight line dan doesn’t have a curve.
That is main properties of vector, STRAIGHT LINE.
How it relate to the subtopic vector (addition and subtraction of vector)???
Let, take a look at it now….
The diagram shows the vectors . Express it terms of
G E F H
SOLUTION: Resultant vector Subtraction of vector Thus, the straight line is the basic concept of vector. By knowing the knowledge of straight line, we know the direction and magnitude of the vector that can be used in the subtopic (addition and subtraction of vector). That why, STRAIGHT LINE is important to vector E F G H
