WebbFor sin 35 degrees, the angle 35° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 35° value = 0.5735764. . . Since the sine function is a periodic function, we can represent sin 35° as, sin 35 degrees = sin (35° + n × 360°), n ∈ Z. ⇒ sin 35° = sin 395° = sin 755°, and so on. WebbThe value of sin12 ∘sin48 ∘sin54 ∘ is equal to. A 32 B 21 C 81 D 31 Medium Solution Verified by Toppr Correct option is C) Consider, sin12 osin48 osin54 o =(sin12 osin48 o)sin54 o = 21(cos(12−48)−cos(12+48))sin(90 o−36 o) ..... [Using sinasinb formula] = 21(cos36 o−cos60 o)cos36 o ........ [∵cos(−x)=cosx and sin(90 o−x)=cosx]
