Question

If f(x)=5 \cos 7 ln (x) Find f²

Answer 1

To find f²(x) given f(x) = 5 cos(7 ln(x)), square each term in the function and simplify the equation to get f²(x) = 25 cos²(7 ln(x)).

Step-by-step explanation:

To find f²(x) given f(x) = 5 cos(7 ln(x)), we need to square the function. Square each term in the function:

f²(x) = (5 cos(7 ln(x)))²

Apply the square to both the coefficient (5) and the function (cos(7 ln(x)):

f²(x) = 5² * (cos(7 ln(x)))²

Simplify the equation:

f²(x) = 25 * cos²(7 ln(x))

Therefore, f²(x) = 25 cos²(7 ln(x)).
