Thanks for your nice and creative strategy. :biggrin:

I'm going to get my BS at the age 22, so I think that you are now well ahead of me. :bugeye:

Yes, physicists do earn money. :wink: Here is the facts and figures of career in physicist. # of people in profession: 18,000 Average hours per week: 40 Average starting salary: $38,500 Average salary after 5 years: $65,000 Average salary after 10 to 15 years: $85,000+

here is what i got (cos x / sin x ) / (cos x - sin x / cos x ) + (sin x / cos x) / (sin x - cos x / sin x) = (cos x / sin x )*(cos x / cos x - sin x) + (sin x / cos x)*(sin x / sin x - cos x) = (cos ^2 x / cos x - sin^2 x) + (sin^2 x / sin x - cos^2 x) = (sin^2 x - 1 / cos x - sin^2 x ) +...

Here is what i got by working on the right hand side. (cot x / 1- (sin x / cos x)) + (tan x / 1 - (cos x / sinx)) = (cot x / (cos x - sin x / cos x)) + (tan x / (sin x - cos x / sin x)) then i tried several different ways to work on the problem from this step, but it never worked.

Can anyone help me sove this problem? cot x + tan x + 1 = (cot x / 1 - tan x) + (tan x / 1 - cot x)

I just figured out how to work on the problem. thanks everyone for helping me.

HI guys, I'm really confusing about this Q., and I hope you guys can give me some help. :smile: - Find the perimeter and the area of a regular pentagon inscribed in circle of radius 9.
