Let \(f\) and \(g\) be periodic functions with the periods \(T_{1}\) and \(T_{2}\) respectively. Then \(f+g\) is
- A periodic with period \(\mathrm{T}_{1}+\mathrm{T}_{2}\)
- B non-periodic
- C periodic with the period \(\mathrm{T}_{1}\)
- D periodic when \(T_{1}=T_{2}\)
Answer & Solution
Correct Answer
(D) periodic when \(T_{1}=T_{2}\)
Step-by-step Solution
