Can anyone tell me how to convert this parametric equation to cartesian (x,y)? r(t)=<2.5+2cos(4t),2.1+1.23sin(4t)> I've tried so many ways and they're incorrect.

Thanks for the confirmation and advice. Also can you explain to me what the answer actually means? I'm asked "How do you interpret the results?" But I don't exactly know what vector projections actually are. Thanks in advance

Homework Statement In three dimensions, consider the vector V = a1i + a2j +a3k. Determine the projections of V onto the x, y, z axis. Homework Equations These are formulas from my textbook related to projection: All underscores mean subscript. Proj_A B = (B * A/|A|) A/|A| = ((B * A)/(A * A))...
