The equation is:

Is it true I have written?

```
Double x = 14.26
Double y = -1.22
Double z = 3.5 * Math.Pow(10.0, -2)
Double t;

t = ( 2 * Math.Cos( x - Math.PI / 6 ) ) / ( 0.5 + Math.Pow( Math.Sin( y ), 2 ) ) * ( (1 + Math.Pow( z, 2 ) ) / ( 3 - Math.Pow( z, 2 ) / 5 ) );

```

Because the result does not coincide with the above desired result -- t = 0,188451240697501, and I need to t deduced 0.564849.
