ii) sec^2 45 degree - tan^2 45 degree
iii) cossec^2 60 degree - cot^2 60 degree

Please answer

Answer 1

Answer:

hey mate here is ur ans

Step-by-step explanation:

all answers is 1

sin²@+cos²@=1

1+tan²@=sec²@

1+cot²@=cosec²@

hope it help u

Answer 2

Answer:

Answers to each question is 1

Step-by-step explanation:

As we know that ;

$\sin^{2} ( \alpha ) + \cos^{2} ( \alpha ) = 1 \\ \sec^{2} ( \beta ) - \tan^{2} ( \beta ) = 1 \\ \csc^{2} ( \gamma ) - \cot^{2} ( \gamma ) = 1$

here alpha , beta , gamma can take any values ;

so answer to all of the above questions is "1".
