This question develops: "compute the dot products of x.x,, y.y, x.y checking that sinx and cosx are orthogonal..x.y=sum(x.y) "
I am really stuck here. Maybe that is my maths. My attempt is as pitifully follows:
#define PI 3.142
//stating variable type and titles of the arrays
float ,sinC, x, y, sumsq, sumsr, sumss;
for(i=0; i<=360; i++)
//shall i define the arrays? or the mulitiplied arrays?
printf("%.2f\t %.2f% %.2f\n",sumq, sumsr, sumss);
