amplitude of 2.5cos(4x)

Solution

amplitude

2.5 cos (4 x)

Solution

2.5

Solution steps

f (x) = 2.5 cos (4 x), A = 2.5

Therefore, the amplitude |A| is

2.5

2.5

Popular Examples

periodicity of f(x)=cos(1/2 x-pi/4)periodicity

f (x) = cos (\frac{1}{2} x - \frac{π}{4})

critical f(x)=(e^x)/(x^2)critical points

f (x) = \frac{e ^{x}}{x ^{2}}

slope of 7x+y=5 slope

7 x + y = 5

extreme g(x)=6x^4+32x^3 extreme points

g (x) = 6 x^{4} + 32 x^{3}
