amplitude of 3cos(4x)

Solution

amplitude

3 cos (4 x)

Solution

3

Solution steps

f (x) = 3 cos (4 x), A = 3

Therefore, the amplitude |A| is

3

3

Popular Examples

extreme f(x)=x^4-18x^2 extreme points

f (x) = x^{4} - 18 x^{2}

domain of f(x)=x^3-3x^2-13x+15 domain

f (x) = x^{3} - 3 x^{2} - 13 x + 15

critical f(x)=x^{5/2}-8x^2 critical points

f (x) = x^{\frac{5}{2}} - 8 x^{2}

distance (1,13),(27,21)distance

(1, 13), (27, 21)

f (x) = ln (x^{2} + 1)
