by Pythagoras identities of trigonometry

Answer 2

Answer:

The value of sec²26° - tan²26° is 1.

Step-by-step explanation:

The basic Pythagorean identities followed in trigonometry are:

• sin²θ + cos²θ = 1
• 1 + tan²θ = sec²θ ⇒ sec²θ - tan²θ = 1
• 1 + cot²θ = cosec²θ ⇒ cosec²θ - cot²θ = 1

Here, 'θ' can take up any value either in degrees or in radians. Whatever be the value, if the equation follows the above identities, then the value would be according to them.
