tan()
Description
Calculates the tangent of an angle (in radians). The result will be between negative infinity and infinity.
Syntax
tan(rad)
Parameter Values
- rad: The angle in radians. Allowed data types: float.
Return Values
- The tangent of the angle. Data type: double.
Example Code
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:
COM6
tan(0°) = 0.00
tan(15°) = 0.27
tan(30°) = 0.58
tan(45°) = 1.00
tan(60°) = 1.73
tan(75°) = 3.73
tan(90°) = -22845570.00
tan(105°) = -3.73
tan(120°) = -1.73
tan(135°) = -1.00
tan(150°) = -0.58
tan(165°) = -0.27
tan(180°) = 0.00
