amplitude of 2cos(4x+pi/2)

Solution

amplitude

2 cos (4 x + \frac{π}{2})

Solution

2

Solution steps

f (x) = 2 cos (4 x + \frac{π}{2}), A = 2

Therefore, the amplitude |A| is

2

2

Popular Examples

y = - 4

asymptotes of 1/(sqrt(1-x^2))asymptotes

\frac{1}{1 - x ^{2}}

parity f(x)=x-3x^3 parity

f (x) = x - 3 x^{3}

perpendicular y= 4/3 x perpendicular

y = \frac{4}{3} x

inverse of y=2x+9 inverse

y = 2 x + 9
