Stu: This is a quadratic equation right?
Can you show me the steps to solve.
y = 2cos(x) + x2 + 2x - 7
Hi Stu,
Where did you dig this up from?
No it is not a quadratic equation. It is not even a quadratic function.
It would be a quadratic function if it did not have the 2cos(x) in it.
As for solving it, there is nothing to solve. It is just y =.
to solve it it would have to be some number equals (without the y)
I graphed this function for you to show you what it would look like.
But that is it from me on this one.
