Why do we write C at every answer in integrals?

Posted by Sahib Singh 3 weeks ago

CBSE > Class 12 > Mathematics

5 answers

Your Buddy 2 weeks, 6 days ago

we write +c integration because :
e.g: the differentiation of 3x+5 is 3 only but if we integrate it our answer will be 3x only then where is our constant value to represent this constant in our answer we use arbitrary constant C in our answer, that's why our correct answer is 3x+C where C is an arbitrary constant

Adarsh Ninja 2 weeks, 6 days ago

C is your arbitrary constant It value can be find out by differential equation. ..

Satyam Suman 2 weeks, 6 days ago

It is a constant Example Differentiation of sinx +6 is cosx and sinx is cosx so we write c as a constant because differentiation of constant is 0

Priyanshu Rawat 2 weeks, 6 days ago

C= constant

Kavya S 2 weeks, 6 days ago

Differentiation of contant gives 0 so while integrating we write plus C

Ok then follow all these things and by time you may score more than expect . Just ncert language is required

Sona ..😊 3 weeks, 4 days ago

M abhi 12 class me hui hu

Technical Mind 3 weeks, 4 days ago

So only 1 month left. I may suggest some things . They will surely help
1. Revise all the theory if possible from NCERT.
2. Derivations are must. Few derivations come in exam
3. Solve all the NCERT question untext and exercise every single question. If you do this , you are sure to get 100% in numericals
4. Try to solve if you get time, previous 10 years of CBSE papers and this years sample paer. This all will help to score more than 90% you need many extra efforts but as time is less so you should not even waste a second now.
