Jika diketahui cot=4/3. Tentukan nilai perbandingan trigonometri lainnya?

Kelas 10 Matematika
Bab Trigonometri

cot a = 4/3 → x/y

r = √(x² + y²)
r = √(4² + 3²)
r = √(16 + 9)
r = √25
r = 5

1] sin a = y/r
sin a = 3/5

2] cosec a = r/y
cosec a = 5/3

3] cos a = x/r
cos a = 4/5

4] sec a = r/x
sec a = 5/4

5] cot a = 4/3

6] tan a = 1/tan a
tan a = 3/4
