sin()

Description

Calcule le sinus d'un angle (en radians). Le résultat sera entre -1 et 1.

Syntaxe

sin(rad);

Paramètres

  • rad: l'angle en radians (float)

Valeurs Renvoyées

  • Le sinus de l'angle (double) (entre -1 et 1)

Exemple

void setup() { Serial.begin(9600); for (int angle = 0; angle <= 180; angle += 15) { float angle_rad = angle * M_PI / 180; float sin_result = sin(angle_rad); Serial.print("sin("); Serial.print(angle); Serial.print("°) = "); Serial.println(sin_result); } } void loop() { }

The result in Serial Monitor:
