What is the main focus of the initial setup in the video?

• Drawing a complete graph of y = tan 2x

• Understanding the concept of asymptotes

• Setting up the problem and graphing a section of y = tan 2x

• Calculating the area of a triangle

What is the asymptote of the function y = tan 2x?

• x = pi/8

• x = pi

• x = pi/4

• x = pi/2

Why is the graph of y = tan 2x described as 'squashed'?

• Because it is reflected over the x-axis

• Because it is shifted upwards

• Because it is compressed horizontally

• Because it is stretched vertically

What is the significance of the triangle formed by the tangent and the axes?

• It helps in understanding the concept of asymptotes

• It is used to calculate the area using base and height

• It is irrelevant to the problem

• It shows the intersection points of the graph

How is the height of the triangle determined?

• By calculating the slope of the tangent

• By using the y-intercept

• By using the x-intercept

• By measuring the distance between asymptotes

What is the base of the triangle in the problem?

• 1 - pi/2

• pi/4

• pi/8 - 1/4

• pi/2 - 1

What is the formula used to calculate the area of the triangle?

• Base times height

• Half of base times height

• Base plus height

• Base minus height

What algebraic technique is suggested to simplify the area calculation?

• Converting to degrees

• Using trigonometric identities

• Factoring out common terms

• Expanding the expression

Why is it important to simplify the area calculation?
