1/secA+tanA
Multiply by secA - tanA on both denominator and nominator
(secA - tanA) ÷ (sec²A - tan²A)
We know, sec²A - tan²A = 1
Then,
(secA - tanA) ÷ 1
SecA - tanA
Multiply by secA - tanA on both denominator and nominator
(secA - tanA) ÷ (sec²A - tan²A)
We know, sec²A - tan²A = 1
Then,
(secA - tanA) ÷ 1
SecA - tanA
