sin(pi+x)^(two)- two *cos(two hundred and forty)- three *sin(seven *pi/ two)+cos(pi-x)^(two)= zero
sinus of ( Pi plus x) to the power of (2) minus 2 multiply by co sinus of e of (240) minus 3 multiply by sinus of (7 multiply by Pi divide by 2) plus co sinus of e of ( Pi minus x) to the power of (2) equally 0
