Question

sec² 36 - cot² 54 please tell identities too​

Answer 1

Answer:

1

Step-by-step explanation:

sec^2 36 - cot^2 54

= sec^2 (90° - 54°) - cot^2 54

= cosec^2 54 - cot^2 54

= 1

Answer 2

Answer:

here as we know that cot thita =tan(90-thita)

Step-by-step explanation:

so here

sec²36 -cot²54

sec²36-(cot54) ²

sec²36-(tan90-54) ²

sec²36-tan²36 (as we know that sec²-tan²=1)

so answer is 1
