Cosine definition. Cosine is one of the most basic trigonometric functions. It may be defined based on a right triangle or unit circle, in an analogical way as the sine is defined: The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. cos (α) = adjacent / hypotenuse = b / c.

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.

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.

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.
