Question

Prove cot^2theta-1/sin^2theta=-1
someone please answer this question ​

Answer 1

Step-by-step explanation:

Bro i feel that it should be cos instead of cot.

Given,

$\frac{{cos}^{2}(Ѳ)-1}{{sin}^{2}(Ѳ)}$

we know that,

$\bold{\boxed{{cos}^{2}(Ѳ)-1={sin}^{2}(Ѳ)}}$

$\frac{{sin}^{2}(Ѳ)}{{sin}^{2}(Ѳ)}$

$=1$
