Question

find the lag: y= 4cos(3 πx+5)


5/3 to the right
3 to the left
5 to the right
5 / 3 π to the left

math precalculus

Answer 1

Answer #1

standard form

y = Acos(B(x-C))+D where C is lag

so,

y = 4cos(3 $\pi$ x+5)

rewrite it

y = 4cos(3 $\pi$ (x +5/3 $\pi$ ))+0

on comparing with standard form

lag = 5/3 $\pi$ , left ( answer)
