sin()

Descrição

Calcula o seno de um ângulo (em radianos). O resultado é dado entre -1 e 1.

Sintaxe

sin(rad)

Parâmetros

  • rad: O ângulo em radianos (float).

Retorna

O seno do ângulo (double).

Código de Exemplo

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:
