Yes.

This shows that the constant is around 0.7169229431689353

How do I show that g(x) = cos(tan(sin ..... cos(tan(sin(x)))) .... ) ) is a constant?

I wish you told me earlier. I was having trouble solving these. Thanks smile

He is preparing for a chemistry test.

So, he is solving problems like this for a change:

What is the minimum volume of water required to dissolve 1g of Calcium sulphate at 298 K. For calcium, K_sp = 9.1 * 10^-6

Isosceles.

Why are you not doing the experiments instead of asking?

#9 Re: Help Me ! » About square, rhombus, rectangle and parallelograms » 2015-02-19 06:00:33

1. Yes, if you add them

2. Could be equilateral but not all the time. Usually isosceles.

3. Isosceles

No, they are not.

Is having a carrot in a box and a carrot in a box in a box the same?

Please make a new thread in the help me section

I do not think going all over them manually is a good idea. I believe that such things are done in reality with computers.

I got 650 results.

May I ask you how you are going to analyse such large blocks of data?

#14 Re: Help Me ! » Trig Equation » 2015-02-09 12:46:38

That is a good idea. Why didn't I think of graphing it?

#15 Re: Help Me ! » Trig Equation » 2015-02-09 03:58:01

No, I received a text asking me to do this or post it.

I texted back why he needed this.

He said that he challenged himself to solve it because he has "trigonometric inverse functions in his syllabus".

I do not think there is a 'nice' method to do this but that is just me.
