Answer 1

Answer:

We are given that,

• Sec A + Tan A = p

We are required to find the value of:

• Sec A - Tan A

We know that,

→ Sec²A - Tan²A = 1

Expanding the above identity we get,

→ ( Sec A + Tan A ) ( Sec A - Tan A ) = 1

Substituting ( Sec A + Tan A ) as p, we get:

→ p ( Sec A - Tan A ) = 1

→ Sec A - Tan A = 1/p

Therefore the value of ( Sec A - Tan A ) = 1/p

Some important Trigonometric Identities:

• Sin²A + Cos²A = 1
• Sec²A - Tan²A = 1
• Cosec²A - Cot²A = 1
