John Says That the Value of the Function Cos[ $\omega$

question 43

Multiple Choice

John says that the value of the function cos[ $\omega$ (t + T) + $\varphi$ ],obtained one period T after time t,is greater than cos( $\omega$ t + $\varphi$ ) by 2 $\pi$ .Larry says that it is greater by the addition of 1.00 to cos( $\omega$ t + $\varphi$ ) .Which one,if either,is correct?

• A)John,because \( \omega \)T = 2 \(\pi\).
• B)John,because\( \omega \)T = 1 radian.
• C)Larry,because \( \omega \)T = 2 \(\pi\).
• D)Larry,because \( \omega \)T = 1 radian.
• E)Neither,because cos(\(\theta\) + 2\( \omega \))= cos\(\theta\).
