If x= sec e- tane and = cosec + cot , then prove that +1yx​

Answer 1

Answer:

Step-by-step explanation:

Answer:

Given:  and  

We have to prove:- xy + 1 = y - x

proof:

If  

Since,  and  

Take L.C.M in above expression,

Since,  and  

Dividing numerator and denominator by  

Now, simplify the y,

Since,  and  

Take L.C.M in above expression,

Now, replace  in  by y

we get  

we need to prove xy+1=y-x

L.H.S

xy + 1

R.H.S

y - x

L.H.S = R.H.S

Hence proved
