A function g is defined by g:x→3−2sinx,for 0◦ ≤x≤A◦,where A is a constant.
Crank
<span>hmmm: g maps x onto 3-2sin(x) for all x from 0 to A degrees g(x) = 3-2sin(x) the inverse would have to be arcsin (3-x)/2, which only has a radian output between -pi and pi i believe. but this is just from memory</span>
