Second Order Differential Equation

Question

0 个投票

y''+3y'-6=0

y(0)=2

y'(0)=3

I have to solve this equation.

Just got an exam today from it and I couldn't solve it, so I failed it.

I have to build the algorithm to get it, but because I'm new to it so I don't know to do this.

->>> Did something really wrong that I didn't get any resoult.

And if you could show me more examples of this types of equations and how I cand solve them, it would be great. I can't really get them.

Thank you very much for your help!

function dy=test(t,y)   
dy=zeros(2,1);  
dy(1)=y(2); 
dy(2)=y(1)+3.*y(2)-6; 
end

https://in.mathworks.com/help/matlab/ordinary-differential-equations.html - there are plenty of examples there , you were so close by the way , I’m pretty sure you’re capable of learning once you go through that link

I can't thank you enough for your answer.

I hope I'll manage to learn it.

Thank you very, very much!
