fiitjee

hey anyone please?????????????

xsin-ycos = ^{[ ]}x²+y²

sin²/a + cos²/b = 1/x²+y²

on eliminating you get

x²/a² + y²/b² = C

FIND C ????

tell the question !!!!!!!!!!

1. take conjugate

(secA-tanA) (secA+tanA)/(secA-tanA)

=sec²A-tan²A/secA-tanA

=1/secA-tanA (since sec²A-tan²A =1)

it is the same for next also.

i hope iam correct.rate me if it is

useful .

cheers!!!!!!!
