Write the x value in the unit circle in terms of theta the measure of the central angle

  x = cos(θ)

Step-by-step explanation:

The above relation is one that is usefully committed to memory. The mnemonic SOH CAH TOA can help you remember it, along with ...

  y = sin(θ)

The x-value is adjacent to the central angle; the y-value is opposite. The hypotenuse of the relevant triangle in a unit circle is 1.

The x-value is ...

  x = cos(θ)

These relationships are necessary to convert from rectangular to polar coordinates and vice versa. They are also helpful when working vector problems.
