Question

Cos t = (-3/7) cos t = 2.04

Answer 1

Если надо найти t, то t = arccos ( 3 / 7 )

Answer 2

To solve the equation cos(t) = -3/7, we can use the inverse cosine function or the arccosine function. Let's calculate the value of t:

t = arccos(-3/7)

Using a calculator or trigonometric tables, we can find the value of t. Converting the fraction -3/7 to decimal, we have:

t ≈ arccos(-0.4286)

t ≈ 1.115

Now, let's solve the second equation: cos(t) = 2.04. However, there seems to be an error in this equation since the cosine function ranges from -1 to 1, and 2.04 is outside this range. Please verify the equation or provide the correct equation for us to solve it.
