Answer:
Step-by-step explanation:
प्रश्नानुसार sinx + sin3x + sin5x = 0
या ( sinx + sin5x ) + sin3x = 0
या
या 2 sin3x cos(-2x) + sin3x = 0
या 2 sin3x cos2x + sin3x = 0
या sin3x ( 2 cos2x + 1 ) = 0
अतः या तो sin3x = 0 या 2 cos2x + 1 = 0
⇒ sin3x = 0 या cos2x = -1/2
⇒ sin3x = 0 या cos2x =
⇒ sin3x = 0 या cos2x =
⇒ 3x = nπ या 2x =
⇒ x = या x= ,n∈Z
