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

cos 75 + cos 45 = cos 15
We know that: cosx + cosy = 2cos(x+y)/2 * cos(x-y)/2. Then : cos75+cos15= 2 cos(75+15)/2 * cos(75-15)/2 = 2cos(90/2) * cos(60/2) = 2cos(45)*cos(30) = 2(sqrt2)/2.
Cos 15 dan Cos 75 YouTube
untuk mengerjakan soal ini maka kita harus mengetahui rumus identitas trigonometri yaitu cos a ditambah cos b = 2 cos a + b 2 dikali cos A min b per 2 maka dari itu kita bisa langsung masukkan saja angka-angkanya dengan a = 75 derajat dan b = 15 derajat sehingga menjadi cos 75 derajat + cos 15 derajat = 2 cos 75 derajat + 15 derajat per 2 dikali dengan cos 75 derajat dikurang 15 derajat per 2.

To find cos(15°), you can use a half angle identity or a difference identity. The same is true for cos(75°). The difference sin(15°) - cos(75°) is probably most easily found with the sum to product identity:
without using trigonometric table evaluate . sin 75× cos 15 + cos 75 . sin Brainly.in
The product to sum identity is useful here: cos (α)cos (β) = (1/2) (cos (α+β) +cos (α-β)) cos (75°)cos (15°) = (1/2) (cos (90°) +cos (60°)) = (1/2) (0 + 1/2) = 1/4. This product of cosines is 1/4. Yah no problem Thanks for the help. report flag outlined. Thank you for the Brainliest.
