Question

1-tan^2ø by cot^2ø-1= tan^2ø​

Answer 1

Answer:

tan²∅

Step-by-step explanation:

1-tan²∅ ÷ cot²∅-1

= 1 - tan²∅ ÷ 1 upon tan²∅ -1       from cot²∅ = 1 upon tan²∅

=  1 - tan²∅÷ 1 - tan²∅ upon tan²∅     by cross multiplication

then tan²∅ will go up and

1 - tan²∅÷ 1 - tan²∅ will get cancelled

and you will get

tan²∅
