Question

Функцію задано формулою (f)=4sinx-0,5sin2xcosx Знайти нулі функції

Answer 1

Відповідь:

x=πn, де n ∈ Z

Покрокове пояснення:

4sinx-0.5sin2x*cosx=0

4sinx-sinx*cos²x=0

sinx(4-cos²x)=0

sinx=0     або          4-cos²x=0

x=πn, де n ∈ Z        cos²x=4

                                cosx=±2

                                x ∈ ∅

Answer 2

Finding the Zeros of the Function

The given function is f(x) = 4sin(x) - 0.5sin(2x)cos(x). To find the zeros of the function, we need to determine the values of x for which f(x) equals zero.

Unfortunately, the search results did not provide specific information about the zeros of the given function. However, we can still attempt to find the zeros by solving the equation f(x) = 0.

Let's set f(x) equal to zero and solve for x:

4sin(x) - 0.5sin(2x)cos(x) = 0

Since the equation involves trigonometric functions, it may not have a simple algebraic solution. We can use numerical methods or graphing techniques to approximate the zeros of the function.

One common numerical method is the Newton-Raphson method, which involves iteratively improving an initial guess to find the zeros of a function. However, without an initial guess or more specific information, it is challenging to provide an accurate solution.
