1IT IS A SIMPLE 1
I AM GETTING (A)
WHAT I USED THE FACT IS A TRIANGLE
MAKE A TRIANGLE U WILL GET THE ANSWER
11so from there we get
sin{2cos-1(1-x2/2x)}
then?
please bear with me this might be very silly :(
1dude u r smart
put the values if u don't want to solve it fully
and no question is silly
every thing has its own importance
if u wish to solve it fully then as u wish [1]
