Question

(cos3п/2+2x)=cosx c объяснением,пожалуйста)

Answer 1

(соs 3п/2+ 2х)=соsx
[cos 3п/2= 270 °,следователь соs меняем на sin, + 2Х значит это получается 4 четверть, но т.к.cos в 4 четверти полож-ый то sin оставляем полож-ым].
Получается:
sinX=cosX|÷sin
X=cos÷sin
x=ctg.

Answer 2

Solving the Equation (cos(3π/2) + 2x) = cos(x) + c

To solve the equation (cos(3π/2) + 2x) = cos(x) + c, we need to find the value of x that satisfies the equation. Let's break down the steps to solve it:

Step 1: Simplify the equation We can simplify the equation by evaluating the trigonometric functions and combining like terms.

The value of cos(3π/2) is -1, so the equation becomes: -1 + 2x = cos(x) + c

Step 2: Rearrange the equation To make it easier to solve, let's rearrange the equation by moving all the terms involving x to one side and all the constant terms to the other side:

2x - cos(x) = c - (-1)

Step 3: Solve for x Unfortunately, there is no simple algebraic solution for this equation. We can use numerical methods or approximation techniques to find an approximate solution. One common method is the Newton-Raphson method, which involves iteratively improving an initial guess for the solution.

Without more information about the value of c or any other constraints, it is not possible to provide an exact solution. If you have specific values for c or any other constraints, please provide them so that we can assist you further.
