Learn to evaluate the half angle for tangent on the unit circle

The video tutorial explains how to simplify a trigonometric expression involving cosine and sine. It starts with the expression 1 minus cosine of U divided by sine of U, identifies the coordinate point, and simplifies the expression by combining terms and rewriting fractions. The tutorial concludes with the final simplified expression.

What is the coordinate point identified in the expression 1 minus cosine of U divided by sine of U?

• (-1/2, -√3/2)

• (√3/2, 1/2)

• (1/2, √3/2)

• (-√3/2, -1/2)

How is the number 1 rewritten during the simplification process?

• 1/1

• 3/3

• 4/4

• 2/2

What happens to the signs when dividing two negative numbers in the expression?

• They become positive

• They cancel out

• They become zero

• They remain negative

What operation is performed when dividing a fraction by another fraction?

• Divide by the reciprocal

• Add the fractions

• Multiply by the reciprocal

• Subtract the fractions

What is the final simplified result of the expression?

• -2 - √3

• 2 - √3

• -2 + √3

• 2 + √3
