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:
COM6
sin(0°) = 0.00
sin(15°) = 0.26
sin(30°) = 0.50
sin(45°) = 0.71
sin(60°) = 0.87
sin(75°) = 0.97
sin(90°) = 1.00
sin(105°) = 0.97
sin(120°) = 0.87
sin(135°) = 0.71
sin(150°) = 0.50
sin(165°) = 0.26
sin(180°) = -0.00
