Answer 1

Answer:

sec² 26° - tan²26°

=1

it's formula

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
• 1 + cot²θ = cosec²θ

Here, 'θ' can take up any value either in degrees or in radians, but if the mathematical equation falls under this identity, then the value will be 1.

∴ In this question,

sec²26° - tan²26° = 1
∵ 1 + tan²θ = sec²θ
⇒ sec²θ - tan²θ = 1
