Linear Equations

  1. 1. <ul><li>Form 2: Linear Equation </li></ul><ul><li>Definition of linear algebraic expression: </li></ul><ul><li>Consist of 2 or more linear algebraic </li></ul><ul><li>terms raised to the power of one and </li></ul><ul><li>are combined by addition or subtraction or both. </li></ul><ul><li>Example: </li></ul>
  2. 2. <ul><li>How it is related to the Vector in the topic of </li></ul><ul><li>addition and subtraction? </li></ul><ul><li>Look at the next example so that you can see the connection. </li></ul>
  3. 3. <ul><li>Example: </li></ul><ul><li>In the diagram, PQR is the triangle and S is the </li></ul><ul><li>Midpoint of PR. Given that, 4 a and 3 b </li></ul><ul><li>,determine each of the following vectors in term of </li></ul><ul><li>a and b. </li></ul><ul><li>(a) </li></ul><ul><li>(b) </li></ul><ul><li>(c) </li></ul>R S P Q
  4. 4. <ul><li>Answer: </li></ul><ul><li>a) </li></ul><ul><li>b) </li></ul><ul><li>c) </li></ul>Algebraic expression is used Algebraic expression is used
  5. 5. <ul><li>Point To Be Noted </li></ul><ul><li>As we can see, in vector, we use a lot of algebraic expressions. The above example is only one example. There are more examples of the connection between the linear equation chapter in form 1 and the vector chapter in additional mathematics for form 5. </li></ul>
