WebThe sin of 9pi/4 equals the y-coordinate(0.7071) of the point of intersection (0.7071, 0.7071) of unit circle and r. Hence the value of sin 9pi/4 = y = 0.7071 (approx) Sin 9pi/4 in Terms of … 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°
