Answer 1

Answer:

ok listen here in expression they have taken

AB² out of the square root,so it becomes AB

then, as AC² doesnt have AB² they divided it by AB² (is u dont understand why they divided it u should go to 5th and revise cos thats the basics)

and thats how we get the expression AB $\sqrt{1-AC^{2}/AB^{2} }$
