Find the value of given trigonometric ratio. Given trigonometric ratio: sin 75 ∘. sin 75 ∘ can be expressed as, sin 75 ∘ = sin ( 45 ∘ + 30 ∘) We know that sin ( A + B) = sin A cos B + cos A sin B. So by applying the above formula we get, sin 75 ∘ = sin 45 ∘ cos 30 ∘ + cos 45 ∘ sin 30 ∘. As, sin 45 ∘ = 1 2, cos 30 ∘ = 3 2.

Sine and cosine are the fundamental trigonometric functions arising from the previous diagram:. The sine of theta (sin θ) is the hypotenuse's vertical projection (green line); andThe cosine of theta (cos θ) is the hypotenuse's horizontal projection (blue line).We can rotate the radial line through the four quadrants and obtain the values of the trig functions from 0 to 360 degrees, as in the.

To find the value of sin 75 degrees using the unit circle: Rotate 'r' anticlockwise to form a 75° angle with the positive x-axis. The sin of 75 degrees equals the y-coordinate (0.9659) of the point of intersection (0.2588, 0.9659) of unit circle and r. Hence the value of sin 75° = y = 0.9659 (approx)

Calculate sin(75)° Determine quadrant: Since 0 ≤ 75 ≤ 90 degrees it is in Quadrant I sin, cos and tan are positive. Determine angle type: 75 90°, so it is acute sin(75) = 0.96592582590194 Write sin(75) in terms of cos Since 75° is less than 90. We can express this as a cofunction sin(θ) = cos(90 - θ) sin(75) = cos(90 - 75) sin(75.

How to calculate values of sin75 / cos 75 using Trigonometry identities? YouTube
Answer: Using the values of sin 75 and cos 75 we can compute the value of the product sin 75 cos 75. As we know from above that sin 75 = (√3+1)/2√2 and cos 75 = (√3-1)/2√2, so we get that. sin 75 cos 75 = (√3+1)/2√2 × (√3-1)/2√2. = [ (√3-1) (√3-1)] / (2√2)2. = [ (√3)2 - 12] / 8 by the formula of a 2 -b 2. = (3-1)/8.
