### Cos 45 Degrees Value of cos 45 with proof Examples and FAQ

Cos 45 degrees In a 45 degrees right-angled triangle the cosine of angle 45° is a value representing the ratio of the length of the adjacent side to the length of the hypotenuse (of angle θ). In trigonometry we write the cosine of angle 45° mathematically and its exact value in fraction form is 1/√2.

### Tan 45 Degrees – Find Value of Tan 45 Degrees | Tan 45°

To find the value of tan 45 degrees using the unit circle Rotate ‘r’ anticlockwise to form 45° angle with the positive x-axis. The tan of 45 degrees equals the y-coordinate (0.7071) divided by x-coordinate (0.7071) of the point of intersection (0.7071 0.7071) of unit circle and r. Hence the value of tan 45° = y/x = 1.
