The following point lies on the unit circle. Determine the unknown value., quadrant II

To determine the unknown value of a point on the unit circle in quadrant II, we start by recalling that points on the unit circle satisfy the equation:

$x^2 + y^2 = 1$

In quadrant II, the x-coordinate is negative and the y-coordinate is positive.

Step 1: Break Down the Problem

1. Identify the coordinates given for the point on the unit circle.
2. Determine which coordinate is unknown (either $x$ or $y$).

Step 2: Relevant Concepts

1. Use the unit circle equation: $x^2 + y^2 = 1$.
2. Determine the signs of $x$ and $y$ in quadrant II.

Step 3: Analysis and Detail

1. Substitute the known coordinate into the unit circle equation.
2. Solve for the unknown coordinate.

Step 4: Verify and Summarize

1. Check the calculated unknown value to ensure it satisfies the unit circle equation.
2. Confirm that the signs of the coordinates are appropriate for quadrant II.

Final Answer

If, for example, we have $y = 0.6$ and need to find $x$:

1. Substitute $y$ into the equation: $x^2 + (0.6)^2 = 1$ $x^2 + 0.36 = 1$ $x^2 = 1 - 0.36$ $x^2 = 0.64$ $x = -\sqrt{0.64} = -0.8 \quad (\text{since } x \text{ is negative in quadrant II})$

Thus, the coordinates of the point on the unit circle in quadrant II would be $(-0.8, 0.6)$.

If you provide the specific known component (either $x$ or $y$), I can give the exact numeric answer.
