Write an expression as a single function using the sum and difference formulas

The video tutorial explains the concept of tangent and how to determine whether to add or subtract angles using the tangent formula. It guides the viewer through identifying angles U and V and demonstrates calculating the tangent of 66 degrees by adding 19 and 47 degrees.

What is the first step in determining whether to add or subtract angles when dealing with tangent?

• Determine if the operation is addition or subtraction

• Check the tangent formula

• Calculate the tangent value

• Identify the angles involved

In the tangent formula, what does adding in the numerator indicate?

• Adding the angles

• Dividing the angles

• Multiplying the angles

• Subtracting the angles

What is the result of adding 19 degrees and 47 degrees in the context of tangent?

• Tangent of 66 degrees

• Tangent of 66 radians

• Tangent of 19 degrees

• Tangent of 47 degrees

Which angles are identified as U and V in the final calculation?

• 66 degrees and 19 degrees

• 19 degrees and 47 degrees

• 47 degrees and 66 degrees

• 19 degrees and 66 degrees

What is the final tangent value calculated in the video?

• Tangent of 90 degrees

• Tangent of 66 degrees

• Tangent of 47 degrees

• Tangent of 19 degrees
