Question

If sec A+tan A=1/2. Find the value of sec A-tan A.

Answer 1

Given that,

• sec A + tan A = 1/2

We know that sec² θ + tan² θ = 1. So, we can write it as...

➡ (sec A + tan A)(sec A - tan A) = 1

➡ 1/2 (sec A - tan A) = 1

➡ (sec A - tan A) = 1 - 1/2

➡ (sec A - tan A) = 2 - 1/2

➡ (sec A - tan A) = 1/2

∴ The value of “ sec A - tan A = 1/2 ”.
