6*sin(180*8.5/17)
$${\mathtt{6}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\frac{{\mathtt{180}}{\mathtt{\,\times\,}}{\mathtt{8.5}}}{{\mathtt{17}}}}\right)} = {\mathtt{6}}$$
this is just 6*sin90 = 6*1=6 so this is correct,
in EXCEL the angle has to be entered in radians so this is how to do it.
=6*SIN((PI()/180)*(180*8.5/17))
of couse this can just be simplified to
=6*SIN(PI()*8.5/17)
pi is a function but it has no arguments - that is why your need the empty brackets :)
