Question

Помогите вычислить sint, cost, tgt и ctgt, если t=210

Answer 1

Sin210° = Sin(180° + 30°) = - Sin30° = - 1/2

Cos210° = Cos(180° + 30°) = - Cos30° = - √3/2

tg210° = tg(180° + 30°) = tg30° = √3/3

Ctg210° = (180° + 30°) = Ctg30° = √3

Answer 2

Sure, I can help you with that. However, I believe there might be a typo in your question. Instead of "sint," I assume you meant "sin(t)", and instead of "cost," you meant "cos(t)." Additionally, "tgt" and "ctgt" are not standard trigonometric functions. It's possible that "tgt" refers to "tan(t)" (tangent), and "ctgt" refers to "cot(t)" (cotangent).

Using these assumptions, we can calculate the values:

1. sin(t) (sine): sin(210°) ≈ -0.866

2. cos(t) (cosine): cos(210°) ≈ -0.500

3. tan(t) (tangent): tan(210°) ≈ 1.732

4. cot(t) (cotangent): cot(210°) ≈ 0.577

Please note that trigonometric functions are usually calculated using radians rather than degrees. If you want to calculate trigonometric functions using radians, you need to convert the angle from degrees to radians first:

• 210 degrees ≈ 3.6651914 radians

Then, you can calculate the trigonometric functions using the radian value.
