Question

A=22.5° sin-?cos-? tg-?

Answer 1

Sin a = 0.3827
cos a = 0.9239
tg a = 0.4142

Answer 2

To find the trigonometric functions (sine, cosine, and tangent) of an angle, A = 22.5°, you'll need to know the values of sine, cosine, and tangent for that specific angle.

However, I can provide you with the exact values of these trigonometric functions for some commonly used angles, including 22.5°:

Angle: 22.5° Sine (sin 22.5°) ≈ 0.3827 Cosine (cos 22.5°) ≈ 0.9239 Tangent (tan 22.5°) ≈ 0.4142

Please note that these values are approximate, as they are rounded to four decimal places. In practice, you can use a calculator or a trigonometric table to get more precise values for these trigonometric functions.
