shift 2cos(4x+pi/2)

Solution

shift

2 cos (4 x + \frac{π}{2})

Solution

Phase : - \frac{π}{8}, Vertical : 0

Solution steps

f (x) = 2 cos (4 x + \frac{π}{2})

g (B x - C) = cos (4 x + \frac{π}{2}), B = 4, C = - \frac{π}{2}, D = 0

Therefore, the phase shift

\frac{C}{B}

is

\frac{- \frac{π}{2}}{4}

- \frac{π}{8}

The vertical shift

D

is

0

0
