Final Answer: The real zeros of the function sin(2x)+sin(x) on the interval 0x<2π are 0,1.04719755119660,3.14159265358979, and 5.23598775598299

Steps

Step 1 :We are given the function f(x)=sin(2x)+sin(x) and we need to find the real zeros of this function in the interval 0x<2π.

Step 2 :The real zeros of a function are the x-values for which the function equals zero. So, we need to solve the equation sin(2x)+sin(x)=0 for x in the interval 0x<2π.

Step 3 :Solving the equation gives us the values x=0, x=1.04719755119660, x=3.14159265358979, and x=5.23598775598299.

Step 4 :Final Answer: The real zeros of the function sin(2x)+sin(x) on the interval 0x<2π are 0,1.04719755119660,3.14159265358979, and 5.23598775598299
