Buktikan 1. Tan alfa.cosec alfa=sec alfa Minta tolong dong di jawab kak,,,

Tan alpha x cosec alpha = sec alpha

• ruas kiri = tan alpha x coses alpha
= sin alpha/cos alpha x 1/sin alpha
= 1/cos alpha

• ruas kanan = sec alpha
= 1/cos alpha

Jadi,
Ruas kiri = ruas kanan
1/cos alpha =1/cos alpha

(terbukti)

Semoga membantu
