Diketahui cosinus A=24/25,tentukan A.sinus A B.tangen A C.cotangen A D.secan A E.cosecan A

Sisi Miring = 25
Sisi Alas = 24
Sisi Tegak = 7

Cos = 24/25
Sin = 7 /25
Tan = 7/24
Cosec = 25/7
Sec = 25/24
Cot = 24/7

[tex]cos \: a = \frac{24}{25} [/tex]
sisi samping = 24
sisi miring = 25
sisi depan = 7. (triple pytagoras)

[tex]sin \: a = \frac{7}{25} \\ tan \: a = \frac{7}{24} \\ \cot(a) = kebalikan \: tan \: a = \frac{24}{7} \\ \sec(a) = kebalikan cos \: a = \frac{25}{24} \\ \csc(a) = kebalikan \: sin \: a = \frac{25}{7} [/tex]
