Question

Prove that
sinΘ-cosΘ+1/sinΘ+cosΘ-1= secΘ+tanΘ
​

Answer 1

sin@ - cos@ +1/sin@+cos@-1

1/cos@-cos@+1/sin@+1/sin@ -1

1-cos^2@/cos^2+2/sin@-1

sin^2@/cos^2@+2-1(sin@)/sin@

sin^2@/cos^2@+sin@/sin@

sin^2@/cos^2@+1

sin^2@+cos@/cos^2@

sin^2@/cos^2@+cos@/cos^2@

sin^2@/cos^2@+1/cos^2@

tan^2@+sec^2@

hi my friend in my typed sloution their is no theta so I mentioned @ in the place of theta
