To solve this equation, we first need to rewrite it in terms of the same trigonometric function.
Given:
3 + sin(2x) = 4sin^2(x)
Recall the double angle identity for sine: sin(2x) = 2sin(x)cos(x)
Now substitute sin(2x) with 2sin(x)cos(x) in the equation:
3 + 2sin(x)cos(x) = 4sin^2(x)
Rearrange the equation to set it equal to zero:
4sin^2(x) - 2sin(x)cos(x) - 3 = 0
Now, we can use the trigonometric identity sin^2(x) + cos^2(x) = 1 to further simplify the equation:
4(1 - cos^2(x)) - 2sin(x)cos(x) - 3 = 4 - 4cos^2(x) - 2sin(x)cos(x) - 3 = 1 - 4cos^2(x) - 2sin(x)cos(x) = 0
Since cos(2x) = 1 - 2sin^2(x), we can also express cos^2(x) in terms of sin(x):
1 - 4(1 - 2sin^2(x)) - 2sin(x)cos(x) = 1 - 4 + 8sin^2(x) - 2sin(x)cos(x) = -3 + 8sin^2(x) - 2sin(x)cos(x) = 0
This implies that 8sin^2(x) - 2sin(x)cos(x) + 3 = 0.
Further solving this equation involves finding the roots of this quadratic equation in sin(x) or cos(x) before finding the values of x in the original equation.
