sin 30° + cos 60° + tan 30°/sec 60° cotan 30°

Tentukan nilai dari:

sin 30° + cos 60° + tan 30°/sec 60° cotan 30°

Jawab:

sin 30° + cos 60° + tan 30°/sec 60° cotan 30°

    = (sin 30° + cos 60° + tan 30°) cos 60° tan 30°

    = ( ½ + ½ + √3/3) ½ . √3/3

    = (1 + √3/3) √3/6

    = √3/6 + 1/6

    = 1/6 (√3 + 1)
