Check if a point lies inside a triangle

[@sandeepvedavyas8701]

I am not sure if you are gonna read this but if you do I want you to know that you are doing a great job. Keep it up. Thanks for your contribution.

Welcome :)

@@techdose4u Uh... why do you use the symbol for orthogonality and call it a '1'? It makes your notation very confusing. What symbol do you use for "perpendicular" to? Especially given that you seem to avoid using a very simple '1' symbol to denote the number 1.

Great. video! Can you make a video on how to find if a coordinate point is within/inside a hexagon if you know the center, width and vertices of the hexagon? And, how to find if the coordinate point overlaps/is on the border of the hexagon? Thank you!

[@ris_bo3456]

Straight to the point, the visual explanation was great.

[@qwerty273]

WOW! This is VERY helpful for me, i didn't think of doing it like this, thanks so much!

Welcome :)

Plz include more videos on geometrical algorithms These are the topics u might like to cover Convex hull and line sweep

[@techdose4u]

I will try

If we calculate and a1 a2 a3 and add them then calculate area of whole triangle then there could difference between their precision...in that case what to do?

[@vaibhavkalband6544]

I am facing the same problem

[@techdose4u]

I think you are facing this problem due to division. You can change the formula.....take LCM of denominators and multiply both side. You won't have to divide then. So no problem of precision.

[@harilalmn]

This was so informative.. !! Thanks! I need this logic very much. Now, how can I do the same with a curvy boundary? Please help

[@techdose4u]

Curvy in the sense?

[@harilalmn]

@@techdose4u A boundary made up of curves. Not polygonal...something like an irregular shape or an organic shape.

[@wilmercuevas6491]

Straight to the point, thanks!

Sir plz make video on how recursion works in for loop. I understood if there's single function call but what if recursion is in for loop. How to visualize steps to solve such problem.

[@techdose4u]

So that I think is already explained in permutation video. You can also see string permutation algo. If you have doubt then let me know.

[@ravikumar-nl7zt]

Very tricky and informative. Thanks 😊

Bro which board u r using pl tell the name

[@AnujTiwari-g8o]

great explaination

[@kirtigera2225]

Sir please make next videos on string algorithms like KMP algorithm etc..

[@techdose4u]

Already made with the name sublist search. Please find it in searching algorithms.

[@kirtigera2225]

@@techdose4u yes sir got it..thanks and sir other string algorithms also..

[@techdose4u]

Yea will continue. For now just focussed on mathematical and geometrical algos. Will take a break and then continue making videos :)

@@techdose4u yes sir and thanks for your priceless efforts❤❤

[@liamhaas-neill719]

Does this generalize to 3D irregular polyhedra?

[@techdose4u]

Don't think so

[@vedants.vispute77]

so if the points of the triangle are given, and options are given to check which point lies or not, we have to find out the area of .... this is too much plz tell alternative solution.

[@shawnzhang528]

Visual explanation is good, but no explanation on the math equation.

[@WahranRai]

Did you heard about complexity of algorithms ?

[@AbhaySingh-kj8mb]

Video for interview attending. Le iit jee aspirants yeah wew are here to...

Also.. what is a wertex? I've heard of a vertex.. but never a wertex.

might be easier with x product
