Evaluate using the half angle formula for Tangent

The video tutorial covers the use of angle formulas, focusing on the half angle formula for tangent. It explains how to solve for U, using 30 degrees for simpler calculations, and addresses common mistakes in angle conversion and fraction simplification.

What formula is the teacher asking the students to use instead of the sum and difference angles?

• Pythagorean Identity

• Double Angle Formula

• Law of Sines

• Half Angle Formula

What is the value of 'U' when solving for the angle in the half angle formula?

• 390 degrees

• 195 degrees

• 150 degrees

• 45 degrees

Why is it easier to use 30 degrees instead of 390 degrees in calculations?

• 30 degrees is a smaller angle

• 30 degrees is a more common angle

• 390 degrees is not on the unit circle

• 30 degrees and 390 degrees give different results

What are the sine and cosine values of 30 degrees on the unit circle?

• 0 and 1

• 1 and 0

• sqrt 3 / 2 and 1/2

• 1/2 and sqrt 3 / 2

What is a common mistake when dealing with fractions within fractions?

• Adding instead of subtracting

• Multiplying by the wrong denominator

• Using incorrect trigonometric values

• Forgetting to simplify

What is the final result of the calculation after correcting the mistake?

• 1/2

• sqrt 3 / 2

• 2 - sqrt 3

• 2 + sqrt 3

What is the correct radian measure for 30 degrees?

• π / 3

• π / 2

• π / 4

• π / 6
