There is just one value in the first quadrant where:
sin x = cos x = \frac{ \sqrt{2} }{2}
The point is (\frac{ \sqrt{2} }{2} ,  \frac{ \sqrt{2} }{2}) and x=45°=π/4

Estimate √125 to the nearest integer.
Damm [24]

Given:

The number is \sqrt{125}.

To find:

The estimate value of given number.

Solution:

We have,

\sqrt{125}=\sqrt{5\times 5\times 5}

It can be written as

\sqrt{125}=5\sqrt{5}

We know that, \sqrt{5}\approx 2.236. So,

\sqrt{125}=5(2.236)

\sqrt{125}=11.18

Approx the value to the nearest integer.

\sqrt{125}\approx 11

Therefore, the required integer is 11.

Quick question:)))

First and foremost is the vertex, which is either the highest point or the lowest point of the parabola (which’s is what the graph of a polynomial looks like). From the vertex, you can always determine the next two points closest to the maximum/minimum.

Another key feature includes the y-intercepts, which are important if you want to find the zeros of the polynomial. Sometimes, the x-intercepts may come in handy as well, but not as often as the y-intercepts.
