Shortcut Trick

If sec θ + tan θ = k, then sec θ − tan θ = 1/k.

Given sec θ + tan θ = √3 ⇒ sec θ − tan θ = 1/√3.

Adding both: 2 sec θ = √3 + 1/√3 = 4/√3 ⇒ sec θ = 2/√3.

This corresponds to the standard angle θ = 30°.

Calculation: sin 30° + cos 30° = 1/2 + √3/2 = (1 + √3)/2.

∴ The correct answer is ((1+√3))/(2).

Alternate Method

Given: sec θ + tan θ = √3

Formula Used: sec² θ − tan² θ = 1

⇒ (sec θ + tan θ)(sec θ − tan θ) = 1

⇒ √3 × (sec θ − tan θ) = 1 ⇒ sec θ − tan θ = 1/√3

⇒ Add the equations: (sec θ + tan θ) + (sec θ − tan θ) = √3 + 1/√3

⇒ 2 sec θ = 4/√3 ⇒ sec θ = 2/√3

⇒ cos θ = 1/sec θ = √3/2

⇒ From tan θ = sec θ − 1/√3 = 2/√3 − 1/√3 = 1/√3

⇒ sin θ = tan θ × cos θ = (1/√3) × (√3/2) = 1/2

⇒ sin θ + cos θ = 1/2 + √3/2 = (1 + √3)/2

∴ The correct answer is ((1+\sqrt3))/(2).
