Why do we write C at every answer in integrals?

Posted by Sahib Singh 3 years, 7 months ago

CBSE > Class 12 > Mathematics

5 answers

Tec Om 3 years, 7 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 3 years, 7 months ago

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

Satyam Suman 3 years, 7 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 3 years, 7 months ago

C= constant

Kavya S 3 years, 7 months ago

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