STPM 2017 Mathematics (T) Term 1 Assignment

STPM 2017 Term 1 MT Coursework Explained
03
JULY, 2016
Polynomial
Trigonometry
Transformation
I will start posting Mathematics (T) and Mathematics (M) coursework sample answer again this term. Only sample solution for mathematical part will be posted. Different school teacher have different requirement on the non-mathematical part (Introduction, methodology, and conclusion). That’s why i am not going to write it and post it here. Thanks.
Assignment A: Function (Investigation)
A function is a relation whereby every input gives a unique (exactly one) output. There are four
possible ways to represent a function; verbally, numerically, visually and algebraically.
Numbers

1. Discuss, with examples, the differences between a relation and a function.
2. Give at least five different representations of a simple discrete function.
3. Give at least three different representations of a continuous function.
“Please ask your school teacher for introduction, methodology, and conclusion.”
4. Consider the algebraic function f:x\rightarrow a(x-b)^n+c
Describe, with sketch graphs, the function f for different values of a, b and c for n = 1,2 and 3.
5 Repeat task 4 with the trigonometric function g:x\rightarrow a\sin[n(x-b)]+c.
6 Repeat task 4 with an exponential or logarithmic function of your own choice.
“Please submit your introduction/methodology/conclusions if you wish to share with others by submit a comment below.”
Sample solution for the mathematical part.

For question 1. Please google for the definition.

For question 2. You can assign any functions but make sure your range is “integer”.

For question 3. You also can assign any functions but make sure your range is “any numbers”.

Question 1 2 3
For question 4

For n=1. Some ideas for you. You can try a>0, a=0, a<0, b>0, b=0, b<0, c>0, c=0, c<0. So you will get many combinations. For the total number of combinations, please refer to your school teacher.

For n=2. Same.

For n=3. Same.

I am not going to sketch the graph for n=3. Please do it yourself. Thanks.

For question 5

For n=1. Some ideas for you. You can try a>0, a<0, a>c, c>a, b>0, b<0, b in first/2nd/3rd/4th quadrant. So you will get many combinations. For the total number of combinations, please refer to your school teacher.

In short. a is amplitude. b translation (left/right). c is translation (up/down).

For n=2. Same.

For n=3. Same.

I am not going to sketch the graph for n=2(frequency=2) and 3(frequency=3). Please do it yourself. Thanks.

For question 6

You can consider h(x)=ae^{n(x-b)}+c

For n=1. Some ideas for you. You can try a>0, a<0, b>0, b<0, b>0, c<0, c>0. So you will get many combinations. For the total number of combinations, please refer to your school teacher.

In short. a is scale factor(vertical). n is scale factor(horizontal). b translation (left/right). c is translation (up/down).

Knowledge.

    Sir
    My school teacher she won’t discuss any introduction, methodology and conclusion for our coursework.
    Could you at least give some guidance on how to write those things??
    Thank you

    Do we have to write a small conclusion for every graph that is drawn?

    • KK LEE

      It depends on your teacher.

    how i can do question four using microsoft excel. my teacher told us to plot the graph using microsoft excel.

    Reply
    • KK LEE

      You can use the graph function in the excel. Youtube might help you.

    • NavinJ

      ive tried excel for my graphs however it was to no avail because u cant get a graph just by keying in the equation with your chosen values of a b and c. U will need to key in the x-values which is painstakingly time consuming. The beauty of online generated graphs, the equation itself gives u a graph given that u have ur a b and c values. Screenshot and crop or use snipping tool to get the graph on microsoft words and arrange according to your liking. I hope your teacher is not insisting that u use excel and excel only…

  18. NavinJ

    sir, what do you mean by the scale factor for exponential graphs? when n increases, does the scale factor decrease?
