what is an easy way to get the arduino to solve a polynomial of degree 4? Basically I am making a robotic arm, and did the painful inverse kinematics calculations to get a quartic equation, which if I can solve, I can find the right angle to move the servos to.
I need to know all real roots that satisfy the polynomial EQ. I know newton's method could be used but I dont want to have to code that and idk what a great starting point would be. Is there maybe a good library for this?
