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


Law of Cosine (Cosine Law) with Examples and Proof Teachoo

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.

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)

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.

How to calculate values of sin75 / cos 75 using Trigonometry identities? YouTube

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.
