Tipot sumbu Tipot sumbu Maksimum Minimum Maka grafik fungsi tersebut, seperti di bawah ini

Tipot sumbu X comma space open parentheses y equals 0 close parentheses

$table attributes columnalign right center left columnspacing 0px end attributes row y equals cell cos space x end cell row 0 equals cell cos space x end cell row x equals cell straight pi over 2 space a tau space x equals fraction numerator 3 straight pi over denominator 2 end fraction end cell row blank blank cell Titik space open parentheses straight pi over 2 comma space 0 close parentheses space dan space open parentheses fraction numerator 3 straight pi over denominator 2 end fraction comma space 0 close parentheses end cell end table$

Tipot sumbu Y comma space open parentheses x equals 0 close parentheses

table attributes columnalign right center left columnspacing 0px end attributes row y equals cell cos space x end cell row y equals cell cos space 0 degree end cell row y equals 1 row blank blank cell titik space open parentheses 0 comma space 1 close parentheses end cell end table

Maksimum

table attributes columnalign right center left columnspacing 0px end attributes row cell cos space x end cell equals 1 row x equals cell 0 degree space atau space x equals 2 straight pi end cell row blank blank cell Titik space open parentheses 0 comma space 1 close parentheses comma space open parentheses 0 comma space 2 straight pi close parentheses end cell end table

Minimum

table attributes columnalign right center left columnspacing 0px end attributes row cell cos space x end cell equals cell negative 1 end cell row x equals straight pi row blank blank cell titik space open parentheses straight pi comma space minus 1 close parentheses end cell end table

Maka grafik fungsi tersebut, seperti di bawah ini
