shoelace | professionally designed , every day UI components | User Interface library

I use styled-components each component from styled-components I pass in other components, in order to apply them, the problem is that my code looks ugly because every component style I pass in other components it looks like this

SideBarStyledComponents.js

I want to use a sidebar when following links using React Route but when I refresh the page the content disappears

I am using the select Shoelace-element for as agreement checkbox and need to check if it is checked or not. Chrome DevTools shows me the added class "switch--checked" to the label when the switch is checked. It is removed when unchecked.

I need to fire some events when the switch is checked and tried the jQuery hasClass function to do so. I have tried several classes next to the one below. None of it made my event trigger. Please help!

I have a rather complicated problem. Suppose I have the shape below. You can think of the red dot as a person and the pointy shape inside the big polygon as an obstacle. My goal is to compute the total unblocked vision of the person inside the big polygon, which is the area of the polygon minus the red shaded area.

I want to write a function that takes in the coordinates of the person, the coordinates of the ordered vertices of the obstacle(s) and those of the ordered vertices of the big polygon, and returns the area of the unblocked vision.

I have tried multiple things, and I'm aware of the shoelace algorithm, but the only way that I can come up with is through monte carlo. Can I get a hint on a more intelligent and efficient way to compute the area in a closed-form way?

I have a question regarding the edges of an orthogonal polygon. My goal is to decide whether an edge is a top edge (this means the interior of the polygon lies below), a bottom edge (this means the interior of the polygon lies above), a right edge (interior of the polygon is left) or a left edge (interior of the polygon is right).

I have the coordinates of the polygon and sorted them counterclockwise (as this is the usual recommended way).

I wrote some code to calculate the interior of the polygon in Java.

I am new to flask-alchemy. I want to filter a SQL query on the values of a LOC_CODE column. I made db.session.query(schools).filter_by(LOC_CODE='X270').first(). But the compiler returns:

I am in the process of transforming a traditional loop to a foreach loop for solving the shoelace formula problem in R; however, I am not getting the right accumulation with the foreach loop.

Suppose I know 700 different values of x as well as another 700 different values of y coordinates. Every 7 points from my coordinates can construct a polygon. I can easily pick any formula (here I have used shoelace formula) to calculate the area of any polygon. But it's really tough to calculate area of each polygon in this way, is there any good way by which I can calculate the area of all polygon (for this case the total number of polygon is 100) at a time, e.g. by using any iteration.

A simple code is shown below:

I am new to react, I am got stuck with the use of react router links, I don't know what I am doing wrong, hopefully I might get answer here.

I have developed screen, which has a appbar and a drawer which open on click of an icon present in the appbar. this part is working fine. On drawer, I have three links, on click of each link, I want to load other screen on right side of drawer menu. I tried to do it by using react routes here but I got stuck with issues like: You should not use Link outside a Router - Stack Overflow,

I tried to understand answers mentioned for below issue on stackoverflow but was not able to get it correctly. Can you help me how can I use link in ListItems

Below is my code:
