amplitude of-2cos(4pix)

Solution

amplitude

- 2 cos (4 π x)

Solution

2

Solution steps

f (x) = - 2 cos (4 π x), A = - 2

Therefore, the amplitude |A| is

2

2

Popular Examples

f (x) = 2

domain of f(x)=9+6/x domain

f (x) = 9 + \frac{6}{x}

extreme f(x)=x^3+12x+5 extreme points

f (x) = x^{3} + 12 x + 5

extreme f(x)=2x^3+2x^2-2x extreme points

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

inverse of y=(2x)/(x^2+49)inverse

y = \frac{2 x}{x ^{2} + 49}
