Chapter 6, Problem 140

(choose chapter or problem)

In Exercises 139 and 140, use the graphs of \(y_{1}\) and \(y_{2}\) to determine how to change \(y_{2}\) to a new function \(y_{3}\) such that \(y_{1}=y_{3}\).

\(y_{1}=\frac{\cos 3 x}{\cos x}\)

\(y_{2}=(2 \sin x)^{2}\)

Text Transcription:

y_1

y_2

y_3

y_1 = y_3

y_1 = cos 3x / cos x

y_2 = (2 sin x)^2
