Does anyone have an idea how to write a code which differentiate any given equation?

Question

for example:
if we pass a string "2x^2 + 3x"
the code should print 4x + 3

Answer 1

Understood. Thank you for the clarification. I am a person that when I code, I like to make sure I truly understand what is needing coded. :)

I personally don't have any code myself. However, here are a few articles that have some good explanations and details regarding what you are trying to do.

I hope this helps you out and gets you your answer. :)

Answer 2

You stay blessed as well. Good luck with your project and code. :)

Answer 3

Thanks mate...i hope that will help. Stay blessed 😊

Answer 4

I'm a little concerned. How did you come about that answer? is that 2x and you are squaring both the 2 and the x or are you just squaring the x? Your math just seems very off to me. Thanks.

Answer 5

If he wanted to square both the 2 and x he would have written (2x)^2...

Answer 6

I understand. However, you cannot assume they meant that without verifying. It is better to verify than to assume and waste time trying to code something that was wrongly assumed.

@Ryan Wakefield
I understand that people in different places could have different ways of writing, but this "wrongly assumed" and "unverified" syntax of multiplication is widely used in my school. If somebody produces a code which works in the syntax as stated in the question, it will still make sense to me.
If your school uses a different style in multiplication, feel free to tell us the particular method. I would suggest those who provides the answer to specify his/her school or country, if there really exist another way of inputting multiplication syntax into digital device in somewhere else.

Answer 8

if the differentiation is 4x + 3 than one could have easily known that only x is squared, not 2.If still confused you can integrate 4x + 3 back and you will be happy 😊
