Hello, I have tried to print at the serial monitor the cosine of 50 just to make sure that I can use the Math library for my arduino and unfortunately it didn't work.
Here is the code I used.
#include <Math.h>
double dA;
void setup() {
Serial.begin(9600);
dA = cos(50);
Serial.println(dA);
}
There weren't any bugs and uncompilable lines it just showed the wrong answer,
it showed me 0.96 while in reality, the true answer is 0.64.
Does somebody know how to fix that?
