Question

tan theta- cot theta=a
cos theta +sin theta=b

elimination the theta from the question...

Help.plz.

Answer 1

HELLO DEAR,



B=TAN THETA+COT THETA

  =SIN THETA/COS THETA+COS THETA/SIN THETA

=SIN^2 THETA+COS^2 THETA/SIN THETA*COS THETA

=1/SIN THETA*COS THETA

a=SIN THETA+COS THETA

b*(a^2-1)=1/SIN THETA*COS THETA(1+2SIN THETA*COS THETA-1)

            =2


I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

B=TAN THETA+COT THETA

  =SIN THETA/COS THETA+COS THETA/SIN THETA

=SIN^2 THETA+COS^2 THETA/SIN THETA*COS THETA

=1/SIN THETA*COS THETA

a=SIN THETA+COS THETA

b*(a^2-1)=1/SIN THETA*COS THETA(1+2SIN THETA*COS THETA-1)
=2
