Find the exact solutions of sin (2x) - sin (x) = 0 in the interval [0, 2pi)

Sin(2x)-sin(x)=0

2sin(x)*cos(x)-sin(x)=0

sin(x)*(2cos(x)-1) = 0

Sin(x)=0 => x [PiK]
Cos(x)=1/2 => x[Pi/3+(2PiK/3)

K=0 x=0
K=1 x=Pi
K=2 x=5Pi/3

So the answer is 0,Pi, 5Pi/3

Answer x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​

step-by-step explanation:

61/100, because if it is 0.(value) than it is value / 100 assuming value is 2 digits long. we cannot simplify it further because 61 is prime number.
