Statement I: Sine and cosine functions are periodic functions
Statement II: Sinusoidal functions repeat its values after a definite interval of time.

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

Solution

A function f(t) is said to be periodic of time period T if f(t+T) = f(t)
All sine or cosine functions are periodic. Thus, y = A sin $ωt or A \cos ωt is periodic of time period T = \frac{2 π}{ω}$
