Question

sec^2 0-1/cosec^2 0-1 evaluate​

Answer 1

$\huge\mathfrak{\pink{\boxed{\boxed{heya}}}}}$

(sec^2 theta-1)(1-cosec^2theta)=tan^2 theta×(-cot^2 theta) {since sec^2 theta-1=tan^2 theta and 1-cosec^2 theta= -cot^2 theta} =tan^2 theta×(-1)/tan^2 theta= - 1

Answer 2

Answer:

(sec^2 theta-1)(1-cosec^2theta)=tan^2 theta×(-cot^2 theta) {since sec^2 theta-1=tan^2 theta and 1-cosec^2 theta= -cot^2 theta} =tan^2 theta×(-1)/tan^2 theta= - 1
