Question

It's a trignometry question please help me

Answer 1

Answer:

Step-by-step explanation:

cosec A + cot A = m

Now take reciprocal and rationalise, you will get

1/cosec  + cot A = 1/m

cosec - cot / cosec² A - cot² A = 1/m

⇒Cosec A - cot A = 1/m

RHS :-

m ( m - 1/m )/ m ( m + 1/m )

= m - 1/m / m + 1/m

= cosec A + cot A - cosec A + cot A

cosec A + cot A + cosec A - cot A

= 2 cot A / 2 cosec A

= cos A

Hence Proved

I Think Question is

• cosec A + cot A = m

I'm saying this because in my book it's this only,,, And cos A cannot be there in place of cot A.
