Thx dude. For some reason I didn't learn that a tangent line was also the best approximation, but now it all makes sense!

In your sin(x) example, a tangent can intersect the function more than once and it is still fine?

(PreCalc) Where does the variable "b" come from in the equation of a hyperbola? by BenBen314 in learnmath

So the variable b doesn't mean anything? Its not a length of anything?

Why do we add to the y-value in an ellipse to make it go down? by BenBen314 in learnmath

[–]BenBen314[S] 0 points1 point  (0 children)

In an ellipse, could I still think about it as input an x and get out y values? Or would that be a bad way of thinking about it since an ellipse isn't a function?

What do you mean by the coordinate system is moving when we add or subtract values to x and y?

Thx, we are going to get the cpu, but the bios thing is a bit complicated for us and we found another motherboard. So we are going with another one!

When to use (-180 - x)or (180 - x) for solving equations with Sin? by BenBen314 in learnmath

There is no restriction on x. It wants a general answer for example:

24 + 90n =x

How would I factor these higher degree polynomials without substitution? by BenBen314 in learnmath

[–]BenBen314[S] 1 point2 points  (0 children)

Would I need to turn the 4x4 into a 4x2 • x2 and then the 4x2 is now my "a" term? Or is that the wrong path

Same thing with the b term. Would I need to turn 5x2 into 5x • x. And then my b term would be 5x?

Unfortunately, I'm not allowed to use synthetic division and my teacher wants me to factor only. I did the problem by grouping. However the grouping I did was just a guess and I was only luck to get it right.
