Thus, the Solns. are, $x_0, x_1$ , where,

$x_0=0.20002668410486868394424635483808^c,$ &,

$x_1=sqrt(pi-(x_0)^2$ .

$sinx^2=1/25=0.04$

Using Calculator, we find that,

$x^2=0.0400106743539889262206207193469$ .

$:. x=0.20002668410486868394424635483808^c,$

where, $^c$ denotes Radian Measure.

Let us denote, by

$x_0=0.20002668410486868394424635483808^c,$

then, the other solns. in $[0,2pi]$ is, $(x_1)^2=pi-(x_0)^2$ .

Thus, the Solns. are, $x_0, x_1$ , where,

$x_0=0.20002668410486868394424635483808^c,$ &,

$x_1=sqrt(pi-(x_0)^2)$ .

As Respected Zor Shekhtman has pointed out, I have missed two

more solns., which I add here, in his words :

In both cases, for $x_0 and x_1$ , the corresponding negative values are solutions as well: $-x_0 and -x_1.$
