How can I create a function in Python that calculates the cosine from the value of a variable? The variable represents a number in degrees.
Thank you in advance. 😁

The following situation: I want to delete certain folders that keep creating themselves using a batch file. I've already made that progress, and everything's working fine. Now the batch should also be easy to use by other people. The target files are located in the path: C:\Users\USER\AppData\……. What I want now is for the script…
I started programming about six months ago and can now use Python at a pretty good level. I'd like to learn or start using another programming language, but which one? Please tell me why or why not. what about php and java for example? I find it quite interesting

Bots can precisely mimic the behavior of a real user on a website. For example, they can set the User-Agent header to impersonate a browser. They can use a large network of proxies and implement random delays between requests to evade pattern recognition systems. CAPTCHAs can be bypassed using sound or image recognition AIs. What…
The trigonometric functions usually take angles in the “bogen dimension” (“radant”). (angle in arc size = distance divided by radius)
1 full circle = 2 Pi radiant = 360°
You can also convert degrees to Radiant.

If you cannot use the built-in functions:
cos(x) = 1 – x^2 / (1 * 2) + x^4 / (1 * 2 * 3 * 4) – x^6 / (1 * 2 * 3 * 4 * 5 * 6) +- …
This series converges pretty fast.

In C you would write cos(x*pi/180) with pi = 3.1415926 (usw).
Or are you looking for a function that only calculates the cosine with basic calculations? It’ll be a bit more difficult.
