Why do we write C at every answer in integrals?

Posted by Sahib Singh 4 years, 5 months ago

CBSE > Class 12 > Mathematics

5 answers

Tec Om 4 years, 5 months 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 4 years, 5 months ago

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

Satyam Suman 4 years, 5 months 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 4 years, 5 months ago

C= constant

Kavya S 4 years, 5 months 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

Dark ..? 4 years, 5 months ago

M abhi 12 class me hui hu

Technical Mind 4 years, 5 months 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.

Sia ? 4 years, 5 months ago

The matrix I is called an identity matrix because IA = A and AI = A for all matrices A.
This is similar to the real number 1, which is called the multiplicative identity, because 1a = a and a1 = a for all real numbers a.
