Question

If sin x + cos x = a and sec x + cosec x= b then b (a² − 1) =

Answer 1

Step-by-step explanation:

sinx+cosx=a

(sinx+cosx)²=a²

sin²x+cos²x+2sinxcosx=a²

1+2sinxcosx=a²

2sinxcosx=a²-1

sinxcosx=(a²-1)/2

secx+cscx=b

1/cosx+1/sinx=b

(sinx+cosx)/sinxcosx=b

a/(a²-1)/2=b

2a/(a²-1)=b

2a=b(a²-1)
