How would you verify the trigonometric identity 2x = 2sinx cosx

dem82 [27]

Step-by-step explanation:

Hi, there!!

I hope you mean sin2x=2sinx . cosx

so, let's begin in a simple way; by adding, alright:

sin2x= sin(x+x) (as 2x=x+x).

now, let's use compound formula for sin,

so, we get:

sin (x+x)= sinx.cosx + cosx. sinx (as sin(A+B)=sin A. cosB + cosA . sinB)

or, sin (x+x)=2sinx.cosx (adding both).

Therefore, sin 2x = 2sinx. cosx.

Hope it helps..

<h3>hello!</h3>

================================================

These are the current coordinates of the market:-

$\sf{(3,8)}$

Move it 2 units to the left:-

$\sf{(1,8)}$

Move it 3 units down:-

$\sf{(1,5)}\longleftarrow\sf{new~coordinates~of~the~market}$

What was Paul's mistake?

Paul's mistake was:-

He moved the market 3 units to the left and 2 units down, when he should have moved it 2 units to the left and 3 units down.

======================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
