Learn how to use Rhea
Write an equation below. Don't be shy, just try it out! You can find some help on this page: "How to type math equations on Rhea".
You will receive feedback from your instructor and TA directly on this page. Other students are welcome to comment/discuss/point out mistakes/ask questions too!
Answer 1
$ 2+2=4 $
Answer 2
$ x(t)= e^{j t} $
Answer 3
$ 1/2=0.5 $
- Instructor's comments:Another way to write this is: $ \frac{1}{2}=0.5 $. You can also align it like this: $ \frac{1}{2}=0.5 $. -pm
- TA's comments: A easy way to start is to modifying the source code of a existed webpage. For example, homework1 solution. You can check out the source code of the webpage by clicking the "Edit this page" button located at the up-left corner.
- TA's comments: Here is another useful link from wiki listing all the latex code for displaying formula.
Answer 4
$ y(t) = cos(2*pi*t) $
- Instructor's comments: Another way to write this is: $ y(t) = \cos ( 2 \pi t) $. Note that using the * symbol for multiplication is confusing: it usually means convolution. -pm
Answer 5
$ y(t) = sin(2*pi*t) $
- Instructor's comments: Please read the comments above. -pm
Answer 6
$ a^2+b^2=c^2 $
Answer 7
$ E = mc^{2} $
Answer 8
$ f_1(t)=\int_3^5 \sin (x) dx $
Answer 9
$ x = \frac{-b + \sqrt{b^2 - 4ac}}{2a} $
Answer 10
$ cos^2{x}+sin^2{x}=1 $
