>> not Displaying Float

[Reader8765]

I am trying to make a vector class. Here is a simplified version of my code:

#include <iostream>
#include <cmath>
#include <string>

class VectorThree {
    public:
        float x,y,z;
        void rotateZaxis(const float angle);
        friend std::ostream& operator<<(std::ostream& os, const VectorThree& v);
};

void VectorThree::rotateZaxis(const float angle) {
    float oldX = this->x;
    float oldY = this->y;
    float angleSin = sin(angle);
    float angleCos = cos(angle);
    std::cout >> angleSin;
    //this->x = newX;
    //this->y = newY;
};

std::ostream& operator<<(std::ostream& os, const VectorThree& v) {
    os << '<' << v.x << ',' << v.y << ',' << v.z << '>';
    return os;
};

This throws error: no match for 'operator>>' (operand types are 'std::ostream' {aka 'std::basic_ostream<char>'} and 'float') when I call rotateZaxis. What am I doing wrong?

"std::cout << angleSin;" not "std::cout >> angleSin;
cout uses the '<<' insertion operator.

Thanks! I left C++ for a while and am having trouble getting these straight.
