WebFeb 15, 2024 · cos (15π/4) = 1/√2 Method 2: Make use of simple trigonometric identity to calculate the value of cos (15π/4) and sin (15π/4). Here make use of the following identity, sin (2π – θ) = – sin (θ) cos (2π – θ) = cos (θ) Solution: (15π/4) Write (15π/4) as (4π/ – π/4), So, sin (15π/4) = cos (4π – π/4) sin (2π – θ) = – sin (θ) Here, θ = π/4 = 45° WebSo f (4/pi) = tan (1/ (4/pi)). You multiply by the reciprocal and get tan (pi/4). tan (pi/4) = sin (pi/4)/cos (pi/4) = (squareroot2/2)/ (squareroot2/2) = 1 f (4/5pi) = tan (1/ (4/5pi)) = tan (5pi/4) = sin (5pi/4)/cos (5pi/4) = (-squareroot2/2)/ (-squareroot2/2) = 1 namzeric samples for physicians
