WebExample: C sin() function #include #include int main() { double x; double result; x = 2.3; result = sin(x); printf("sin(%.2lf) = %.2lf\n", x, result); x = -2.3; result = … WebFrom cos(α) = a/c follows that the sine of any angle is always less than or equal to one. The function takes negative values for angles larger than 180°. Since for a right triangle the longest side is the hypotenuse and it is opposite to the right angle, the sine of a right angle is equal to the ratio of the hypotenuse to itself, thus equal to 1. cpr certification vacaville https://h2oceanjet.com
