cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
long number
cos67,5
It is: cos(15) = (sq rt of 6+sq rt of 2)/4
Use the half angle form, which states that: sin(x/2) = √((1 - cos(x))/2) Then: x/2 = 157.5 x = 315 You should get: sin(315 / 2) = √((1 - cos(315))/2) = √((1 - 1/√2)/2)
The value of cos 40 degrees is approximately 0.766.
cos 34o ≈ 0.829 cos 34 = 0.86074

Cos(22.5)=0.9238795325
The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.
cos(195) = -0.965925826289
hi,the value of cos 60 is 1/2
When tan A = 815, sin A = 0.9999992 and cos A = 0.0012270 so that sin A + cos A*cos A*(1-cos A) = 1.00000075, approx.
