Do You Evaluate Sin π/2

Answer: The value of sinπ/2 is 1. Sinπ/2 can also be expressed using the equivalent of the given angle (π/2) in degrees (90°).

We know, using radian to degree conversion, θ in  degrees = θ in radians × (180°/π) 

π/2 radians= π/2 × (180°/π) = 90° or 90 degrees 

Therefore sinπ/2  = sin (90°) = 1

Methods to Find Value of Sin pi/2 

The Value of sinπ/2 is given as 1. We can find the value of sinπ/2 by: 

  1. Using Trigonometric Functions 
  2. Using Unit Circle .
