consider the following as regards cumulative disribution function F(x)
- 0 ≤ F(x) ≤ 1
- F(- ∞) = 0
- F(∞) = 1
- F(x1) ≤ F(x2) If x1 < x2

Assertion (A): Fourier series can also be written in exponential form.
Reason (R): sin (n ωt) and cos (n ωt) can be expressed as sum or difference of exponentials.
