Recall

Reciprocal-linear integrals — objective 1

Maths4U Original · Short practice

The integrand is \(\displaystyle f(x)=\frac{4}{x + 3}\), on \(x>-3\).

Find K in the primitive K ln(1x+3)+C on the stated domain.

Enter one exact number or fraction. These checks support non-calculator practice. Give full reasoning separately for written problems.
