me assume that stuf shood be

(1/2)*sine[(pi/2) +20] -2...and that angel be RADIANS

pi/2=1.5707963267948966192313216916397...

add 20 & get angel=21.570796.... rad

angel=21.57079632679489661923...radians

=1235.9155902616464175...deg

divide bi 360 & yu get 3.43309886183790671537767526745

leftover=0.433098861837906715377675267450

become 360*0.4339886... giv 155.9155902616464175 deg

or bout 156 deg

sine(156 deg)=0.40673664307580043

subtrakt 2 & yu get -1.5932633569241996
