#091 Tangent Graphs

How did the presenter find the tangent value?

• The tangent value was found by dividing the value of cosine x by the value of sine x.

• The presenter used a graphing calculator to find the tangent value.
• The tangent value was calculated by dividing the value of sine x by the value of cosine x.

• The tangent value was derived from a complex algebraic equation.

How did the presenter know to place vertical asymptotes on the graph?

• The presenter knew to place vertical asymptotes where the denominator of the function is zero.
• The presenter used a graphing calculator to find vertical asymptotes.
• Vertical asymptotes are always at the x-intercepts of the graph.
• The presenter placed vertical asymptotes where the function is increasing.

 What is the period of the parent tangent function?

• 3π/2

• 2π
• π
• π/2

In the equation y = tan(Bx), how does the value of B affect the period of the function?

• The period is multiplied by B

• The period is divided by B

• The period is added to B

• The period is subtracted from B

When graphing a tangent function, why is it helpful to divide the period by 2?

• To find the midpoint of the function

• To determine the amplitude of the function

• Because half the graph is on each side of the y-axis

• To calculate the frequency of the function
