Cosec(x) +cotan(x)

Cosec(x) +cotan(x)

This is what I got too boss. Thanks �

Eh yes oh, na exactly Wetin me too for get assuming I solve am.

We know that sin^2(x) + cos^2(x)=1

==> sin^2(x)= 1-cos^2(x)

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

==> (sinx)(sinx)= (1-cosx)(1+cosx)

Now divide by (sinx)(1-cosx)

==> sinx/(1-cosx)=(1+cosx)/(sinx)
= 1/sinx + cosx/sinx
= cosecx + cot x

Sin(x)/1-Cos(x)

By rationalising,

Sin(x)/1-Cos(x) X 1+Cos(x)/1+Cos(x)

Multiplying,

Sin(x) + Sin(x)Cos(x) / 1 - Cos²(x)

But Cos²(x) = 1 - Sin²(x)

Factoring out Sin(x)

Sin(x) (1 + Cos(x)) / 1 - 1 + Sin²(x)

1 + Cos(x) / Sin(x)

1/Sin(x) + Cos(x)/Sin(x)

But, 1/Sin(x) = Csc(x)

Cos(x)/Sin(x) = Cotg(x), where g(x) is Cos(x)/Sin(x)

= Csc(x) + Ctg(x)

Which is same as option "C"

Cos(x)/Sin(x) = Cotg(x), where g(x) is Cos(x)/Sin(x)

= Csc(x) + Ctg(x)

Itk, no be the same answer we get

Csc = Cosec

Ctg = Cot/Cotangent

thanks.

You are right

Thanks � guys.

Omo, Kylekent59 solve am in a way you go get "A" for the cource


Femi solve am in a way you go get "C" for the course.


Kylekent I sight you oo. Me too don learn something.

There is nothing like ITK, he solved it rightly and showed workings too.


Must you always have a wicked heart??


He even replied you without insult or any insolent words.

But why everyone dey disturb themselves??,

Since the question has option, just substitute x=30 in the question and write what you get down... Then substitute x=30 in each option, the one that gives you the same answer as your question is the final answer

Ctg should be cotangent

Hmm, wisdom... what do i know...

that's the perfect way to solve, since we are not to show any workings

Ode! You didn't see that he quoted me and others, implying that our workings were wrong cos he didn't know that csc = cosec and ctg = cot/cotangent

You are just poor in analytical reasoning

And you fell to my trap.

I knew it, you wouldn't disappoint.


You are insolent and rude.


Go and learn how to socialise without insulting one.

Bro, that's hw life is. Reason why people don't wanna help or try to do something.

Others are waiting to criticise you.



All the honour should be given to "Femi" not me.

I don't deserve any honours plzz.

Dz guy go don do CBT wella.

But that's the truth bro, no need of you abusing me.
