Prove the trigonometric identity!<br><br> Please help!! 50 Points!
Rudiy27

Answer:

:)

Step-by-step explanation:

For simplicity I will substitue x for β.

1-sin(2x)=(cosx-sinx)^2\\1-2sin(x)cos(x)=cos^2x-2sin(x)cos(x)+sin^2x\\1=cos^2(x)+sin^2(x)\\1=1

In the first step I used the identity

sin(2x)=2sin(x)cos(x)

And I factored out (cosx-sinx)^2

Then it's just simple algebra to cancel till the 3rd step where we used another identity derived from the Pythagorean Theorem.

cos^2(x)+sin^2(x)=1

That's it!

PLEASE HELP! [99 POINTS] !! SERIOUS ANSWERS ONLY !!!

Hello!

We can find out our answer by plugging in the point (1,1) to see which equation works.

y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1

As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.

I hope this helps!
