The sin value = sin(arctan(7/-5)) = (-7/5)/sqrt(1 + (-7/5)^2) = (-7/5)/sqrt(1 + 49/25) = (-7/5)/(1/5)sqrt(25 + 49) = -7/sqrt(74) = -7sqrt(74) / 74
Therefore, the sine value of the function is <span>negative 7 square root 74 divided by 74</span>
well 6 out of 42 is 1/7
double 42 and get 84.
Now to keep it even, you have to multiply 6x2
