Solve this problem using the Trigonometric identities (secA+1)(SecA-1)= tan^2A
2 answers:
Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven
Hope this helps you
Step-by-step explanation:
Here,
LHS
= (SecA+1)(secA -1)


Now, we have formula that:


as we got ,

This is equal to:

= RHS proved.
