Easy Math Editor

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

@tanveen dhingra

Is it just me or is your profile pic really inverted ?

A Former Brilliant Member - 6 years, 2 months ago

HaHa...Ya it is inverted..XD...Even I don't know why so..I put it inverted but every time I try it appears inverted so i gave up and let it be. @Calvin Lin sir why is this happening

tanveen dhingra - 6 years, 2 months ago

Did you upload the pic using "Insert an image" option from B'ant ?

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – There was an option "Upload an Image". I clicked on that. Then I browsed from my folders and selected the picture and clicked on open. It previewed as an inverted image. Then I tried again. Still it came inverted and then i gave up .

tanveen dhingra - 6 years, 2 months ago

@Tanveen Dhingra – Try using any other site for uploading the image .Try this website for uploading your pic .

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – How do I upload it using this site?

tanveen dhingra - 6 years, 2 months ago

@Tanveen Dhingra – I think it'll be clear once you start .

Once there , click on "Browse" button to select the image to be uploaded .
Next up is a CAPTCHA .
After that you'll be redirected to a link where you'll be shown the links generated . Copy the link off the one which says : ".. for MessageBoards,Forums.." : it'll be somewhat like

[IMG]URL[/IMG]

Try it out and if you've got any trouble , ask me , I'll be online for around 15 more minutes:)

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – Ok.Thanks a lot!

tanveen dhingra - 6 years, 2 months ago

@A Former Brilliant Member – What is CAPTCHA. It is nowhere on the site @Azhaghu Roopesh M

tanveen dhingra - 6 years, 2 months ago

@Tanveen Dhingra – Oho! CAPTCHA is that non-sensical dialog box thing , you'll be shown a picture and asked to write what's being shown to you .

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – oops!!..I am sorrry I do not have much info about computer work.

tanveen dhingra - 6 years, 2 months ago

@A Former Brilliant Member – Where do I paste the link?

tanveen dhingra - 6 years, 2 months ago

@Tanveen Dhingra – " ! [] (URL) "

This is the syntax for posting images . I have given given spaces so that you can see the syntax , but when you'll be actually posting it , remove all the spaces.

A Former Brilliant Member - 6 years, 2 months ago

@Tanveen Dhingra – Sorry !! Sorry a million times , I had mistaken your question ! What you are facing is something only a staff member can resolve .

Sorry again , it's just that I got confused from the other comments .

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – ohh.It is okay!!!.I will talk to @Calvin Lin sir for helping me. By the way thank you sooo much for trying to help me!!! :)

tanveen dhingra - 6 years, 2 months ago

A Former Brilliant Member - 6 years, 2 months ago

@A Former Brilliant Member – What is your expected result in IIT Mains?

tanveen dhingra - 6 years, 2 months ago

@Tanveen Dhingra – Well , I haven't really studied a lot . So fir JEE Mains , I just want to get around 250-270 marks , and leave the rest to JEE Advanced .

A Former Brilliant Member - 6 years, 2 months ago

@Tanveen Dhingra – Unfortunately, I am unable to edit your profile pic.

Check the image file that you uploaded, and ensure that it is displaying the image "right-side up". Sometimes, image editors try to be helpful and rotate the file in the way they think you want to view it, so that might be the issue. Try rotating the image 180 degrees and then uploading it again.

Calvin Lin Staff - 6 years, 2 months ago

@Calvin Lin – The image file which I uploaded was totally correct. Do you mean that should I make it tilted and then try?

tanveen dhingra - 6 years, 2 months ago

@Rajdeep Dhingra May I suggest that you post a set containing each of these problems individually as a note, so that others can submit their proofs to these statements? You can also add explanations for the scoring.

Calvin Lin Staff - 6 years, 2 months ago

Sir I have posted the set

Rajdeep Dhingra - 6 years, 2 months ago

Thanks! It's an interesting set of problems.

Calvin Lin Staff - 6 years, 2 months ago

@Calvin Lin – Sir I have released OPC 3
