its corect...(cosx-sinx)^2/cos x=secx-2sinx..
(cosx-sinx)^2/cos x
expandin d numerator..
cos^2x-2cosxsinx+sin^x/cosx=secx-2sinx
since sin^2x+cos^2x=1....
den substitute it...
1-2cosxsinx/cosx=secx-2sinx....
1/cosx-2cosxsinx/cosx=secx-2sinx..
usin trigonometry identity
1/cosx=secx.....
1/cosx-2sinx=secx-2sinx
secx-2sinx=secx-2sinx....PROVED...
i am oau fresher..oo
still learnin frm d bozzezzzzz

Good evening, i need an explanation on convergence and divergence of sequence and series, please

Re: Nairaland Mathematics Clinic by DeeCherry(f): 2:55pm On May 03, 2018

Good afternoon everyone.
i need solutions to these statistical problems.

1. A man has 5 coins, one of which has 2 head, he randomly tosses it 3 times.

a) What is the probability that it will fall head upward all the times?
b)if it always fall head upwards, what is the probability that it is the coin with 2 heads?

2.On probability density fn

a) (x:x > 1/4)

b) (x:x = 1/4)

God bless you
