Find the value of the given expression.
2 × (sin 30° + tan 45°)
Find the value of the given expression.
5 × (cos 60°)
(tan 5x - tan 3x - tan 2x) = ?
Find the value of the given expression.
2 × (sec 60° – sin 30°)

- If sec 2P = sin² 60⁰ + sec 60⁰ - cos² 30⁰, then determine the value of (√3tan P + cot² P)
