amplitude of 2cos(3x+pi/2)

Solution

amplitude

2 cos (3 x + \frac{π}{2})

Solution

2

Solution steps

f (x) = 2 cos (3 x + \frac{π}{2}), A = 2

Therefore, the amplitude |A| is

2

Popular Examples

range of f(x)=|x|-4 range

f (x) = ∣ x ∣ - 4

domain of f(x)=(\sqrt[3]{x-3})/(x^3-3)domain

monotone 9x^{(2)}-x^3-3 monotone intervals

9 x^{(2)} - x^{3} - 3

inverse of f(x)=((4x-1))/((2x+3))inverse

f (x) = \frac{( 4 x - 1 )}{( 2 x + 3 )}

inverse of (x-4)^3 inverse

(x - 4)^{3}
