Question

Вычисли sint и cost, если t может принимать значения −2π?

Answer 1

Как это может? Если он там, то тогда sin = 0, cos = 1

Answer 2

To calculate sin(t) and cos(t) when t can take the value of -2π, you simply need to substitute that value into the trigonometric functions.

Let's start with sin(t):

sin(-2π) = sin(-2 * π)

Since sin(-π) = 0, we know that sin(-2π) will also be 0.

Now, let's calculate cos(t):

cos(-2π) = cos(-2 * π)

Since cos(-π) = -1, we know that cos(-2π) will also be -1.

So the values are:

sin(-2π) = 0 cos(-2π) = -1
