Question

Simplify the expression.

Answer 1

Use the square of a binomial first.

Answer 2

can you simplify it for me?

Answer 3

Then use an identity to simplify it further.

Answer 4

How would I find the max and min values from it ?

Answer 5

I thought it'd be A

Answer 6

How can I know? I don't see the expression any longer.

Answer 7

So I simplified this .. is it correct? y= 2cos(-1/2(x-180^@))-3

Answer 8

Oh Im sorry I sent a screen shot

Answer 9

im confused

Answer 10

The screen shot is not the problem. The problem is I don't see the original question any more. What are you trying to simplify? Where did it go?

Answer 11

no the screen shot is my question lol

Answer 12

ok I am simplifying This: y= 2cos(-1/2x + 90^@) -3

Answer 13

give me the period, amplitude, max/min values, range, domain, horizontal phase shift and vertical displacement.

Answer 14

@cupcakezz
If you have a question, start a post and ask the question. Don't ask your question in the middle of someone else's question.

Answer 15

sorry

Answer 16

so do i expand it of just distribute the exponent?

Answer 17

*or

Answer 18

@isabel_xxvi
For the third time, I can't help you with a problem that I can't see.
What happened to the expression you want to simplify? It's not longer there. I can't see it.

Answer 19

it's the same as the one in the picture (cot x + csc x)^2

Answer 20

how do I start a post ?

Answer 21

Ok, I see it. Sorry. You had it there, and I didn't know.

Answer 22

\( (\csc x + \cot x)^2 \)

Square the binomial:

\(\csc^2 x + 2\csc x \cot x + \cot^2 x\)

Answer 23

\(=1 + \cot^2 x + 2 \csc x \cot x + \cot^2 x \)

\(=1 + 2\cot^2 x + 2 \csc x \cot x\)
