Jawab:

Penjelasan dengan langkah-langkah:

Sec 30° + Sin 45° Csc 45° + Cos 30° Cot 60° = ....

V = akar kuadrat

Sec 30° = 1/cos 30° = 1/(½V3) = 2/V3

Sin 45° = ½V2

Csc 45° = 1/sin 45° = 1/(½V2) = 2/V2 = V2

Cos 30° = ½V3

Cot 60° = 1/tan 60° = 1/V3

Sec 30° + Sin 45° Csc 45° + Cos 30° Cot 60° = (2/V3) + (½V2)(V2) + (½V3)(1/V3)

= (2/V3) + 1 + (3/2)

= (2/V3) + 2½
