Can we start by squarring both sides?

SO CAN we square both sides in this situation as a first stp

[hardy bough]

Aryan bhai ye to thik hai but first step pe sq. Both sides krskte h?

[zealous gate]

$$\left\lvert \frac{1+\cos x}{1-\cos x} \right\rvert = \left(\frac{1}{\sin x}+\cot x\right)^2$$

aL

[zealous gate]

you can square

[hardy bough]

Okk

[fast sandal]

You can, but in basic and most elegant method is that we need to prove that statement so we need to show that LHS statement equals RHS statement. Squaring both sides will meant like we have assumed that equality to be true.

[zealous gate]

yes, the question is can you show an equivalent equality which is "clearly" true

[hardy bough]

Oh

Alr thank you @zealous gate @fast sandal

[zealous gate]

after squaring you can simplify the rhs

[hardy bough]

Yes after squarring its easy

[zealous gate]

$$\frac{1}{\sin x} + \frac{\cos x}{\sin x} = \frac{1+\cos x}{\sin x}$$

[zealous gate]

and all of that squared

[hardy bough]

Yep

Thanks
