Cosine of 105 degrees

WebOct 25, 2015 · sin (105) = sin (15 + 90) = cos 15. First find (cos 15). Call cos 15 = cos x Apply the trig identity: # cos 2x = 2cos^2 x - 1.# cos 2x = cos (30) #= sqrt3/2 = 2cos^2 x - 1# 2cos^2 x = 1 + sqrt3/2 = (2 + sqrt3)/2 cos^2 x = (2 + sqrt3)/4 cos x = cos 15 = (sqrt(2 + sqrt3)/2. (since cos 15 is positive) #sin (105) = cos (15) = sqrt(2 + sqrt3)/2.# WebUse our cos(x) calculator to find the cosine of 115 degrees - cos(115 °) - or the cosine of any angle in degrees and in radians.
