Question

sin2a

Answer 1

Sin2a=Sin(a+a)=SinaCosa+SinaCosa=2SinaCosa

Answer 2

if I remembered that off the top of my head correctly

Answer 3

than you

Answer 4

newton ^3rd law

Answer 5

i just remember the formula. sin2a = 2sinacosa

Answer 6

Newton's 3rd law: f applied = - f applied back lol

Answer 7

sin 4a

Answer 8

\[2\sin 2A \cos 2A\]

Answer 9

Not sure how to put newton's 3rd law, cuz i don't remember exact definitions
@subhabratabehera
I gave u this,
Sin2a=Sin(a+a)=SinaCosa+SinaCosa=2SinaCosa
replace all as with 2as

Answer 10

sin 2a= 2sinacosa
= 2tana/1+tan square a
this is the formula u have to remember n use it in trigonometry,derivatives n integration

Answer 11

sin(a+b)
