$\huge\underline\mathbf\red{L\:H\:S}$

ÀÑswêr:= ~✓✓✓✓✓✓✓✓✓

2sec²∅ - sec²∅ - 2cosec²∅ + cosec⁴∅= sec²∅(2 -sec²∅ - cosec²∅(2 -cosec²∅)

⏩⏩Now we replace

sec²∅ by 1 + tan²∅ and

cosec²∅ by 1 +cot²∅⏪⏪

=>(1+tan²∅)(2-1-tan²∅)-(1+cot²∅)(2-1-cot²∅)✓✓✓

=>(1+cot²∅)(1-tan²∅)-(1+cot²∅)

(1-cot²∅)✓✓✓

=>(1-tan⁴∅)-(1-cot⁴∅)✓✓✓

======cot⁴∅-tan⁴∅======
