tan()

설명

각(라디안)의 탄젠트 계산. 결과는 음의 무한과 무한 사이.

문법

tan(rad)

매개변수

  • rad: 라디안 각 (float).

반환값

  • 각의 탄젠트 (double).

예제 코드

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

The result in Serial Monitor:
