Question

3tg π/4 tg π/3 12sin π/3 cos π/3

Answer 1

1)3 tg П/4=3*1=3
2)tg П/3=корень из 3
3)12 Sin П/3=12*корень из 3/2=12 корней из 3
4)cos П/3=1/2

Answer 2

Let's calculate the values of the trigonometric expressions you provided:

1. tg(π/4): The tangent of π/4 (45 degrees) is equal to 1.

2. tg(π/3): The tangent of π/3 (60 degrees) is √3 (approximately 1.732).

3. 12sin(π/3): The sine of π/3 (60 degrees) is √3/2 (approximately 0.866). So, 12sin(π/3) = 12 * 0.866 ≈ 10.392.

4. cos(π/3): The cosine of π/3 (60 degrees) is 1/2. So, cos(π/3) = 1/2 = 0.5.

Now, you have the values:

1. tg(π/4) = 1
2. tg(π/3) ≈ 1.732
3. 12sin(π/3) ≈ 10.392
4. cos(π/3) = 0.5
