Question

Derive: sin2x=2sinxcosx

Answer 1

(sinx)(cosx)(2)

Answer 2

Thank you! What does "derive" even mean in this situation?

Answer 3

derive refers to the origin in this case, what math class are you in?

Answer 4

Math Analysis so Pre-calc

Answer 5

okay well I used derivative (whether you know them or not) I do not know another way to do it simpler im sorry):

Answer 6

Ok thank you! Also last question what is the "origin?"

Answer 7

It is a double angle formula and when it asks to derive it it's saying how is this equation made, slash prove it using other equations, many equations are made up of smaller ones whether you know it or not

Answer 8

So this question is basically asking to prove that Sin2x is = to 2sinxcosx? I understand that 2sinxcosx is the double angle formula for sin2x

Answer 9

Essentially yes it is saying prove it

Answer 10

Ok thank you!

Answer 11

Im not sure if youre supposed to use equations or just some values
