If cos degree equals to 0.8641
What is Sin degree?
I have no idea how to find this.
Please help me. Thank you
cos^2+sin^2=1
sinDegree=sqrt(1-cos^2degree)
I recognize .8641 as an approximation to √3/2
if cos x = √3/2
x = 30°
sin30° = 1/2 or .5
using your .8641
sinx = .5033
To find the value of sin (degree), we can make use of the Pythagorean Identity, which states that sin^2 (degree) + cos^2 (degree) = 1.
Since we know that cos (degree) equals 0.8641, we can substitute this value into the equation:
sin^2 (degree) + (0.8641)^2 = 1
Now, we can solve for sin (degree).
sin^2 (degree) + 0.7466 = 1
sin^2 (degree) = 1 - 0.7466
sin^2 (degree) = 0.2534
Taking the square root of both sides, we find:
sin (degree) = √0.2534
sin (degree) ≈ 0.5034
Therefore, sin (degree) ≈ 0.5034.
