amplitude of 4cos(x/2)

Solution

amplitude

4 cos (\frac{x}{2})

Solution

4

Solution steps

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

Therefore, the amplitude |A| is

4

4

Popular Examples

slope of x-y=-2 slope

x - y = - 2

critical f(x)=x^4-2x^2+3 critical points

f (x) = x^{4} - 2 x^{2} + 3

extreme f(x)=x+2sin(x)extreme points

f (x) = x + 2 sin (x)

range of f(x)=5+sqrt(4-x)range

f (x) = 5 + 4 - x

range of \sqrt[3]{x}+1 range
