Question

знайдіть похідну складеної функції f(x)=cos(4x-1) у точці x_{0}=pi/4

Answer 1

Ответ:f(x) = cos(4x - 1)

To find the value of f(x) at x = π/4, substitute π/4 into the equation:

f(π/4) = cos(4(π/4) - 1)

f(π/4) = cos(π - 1)

Using the tool, we can calculate the result:

f(π/4) ≈ -0.5403023058681397
