cos(25o) = 0.906307787 ==========
cos 34o ≈ 0.829 cos 34 = 0.86074
cos 315 degrees is 4th quadrant same as cos (-45) degrees which is +0.7071

The exact value is an irrational number, and can't be written on paper with digits.0.34202 is less than 0.000042 percent wrong.Cos(70 deg) is an irrational number and it is impossible to give its exact value.
The value of cos 40 degrees is approximately 0.766.
cot 70 + 4 cos 70 = cos 70 / sin 70 + 4 cos 70 = cos 70 (1/sin 70 + 4) = cos 70 (csc 70 + 4) Numerical answer varies, depending on whether 70 is in degrees, radians, or grads.
