What is the value of cosθ if the terminal side of θ and the unit circle intersect at point (12√,−12√) .(1 point) Responses 12√ Start Fraction 1 over Start Root 2 End Root End Fraction −12 negative Start Fraction 1 over 2 End Fraction 12 Start Fraction1 over End Fraction −12√
The point (12√, -12√) is in quadrant III of the unit circle, which means the x-coordinate is negative and the y-coordinate is negative.
The cosine function is equal to the x-coordinate of the point on the unit circle.
Therefore, the value of cosθ at this point is -12√.
