It makes my problem in math easier, eSSENTIAL app for students, can do pretty much all high school math and below, yeah you may have to pay for the premium but honestly it will be worth it, this app has helped me out in my math classes alot! No way I'd be passing without it.

It is the most reasonable math app I've seen, and 'This app Plus' is available for free in the lockdown. Also I'm very glad that there isn't too many ads on this app. My school is kind of built like a whole bunker so sometimes my problems won't fully go through.

Using the linear approximation, we can estimate √9.1 by writing √9.1 = f(9.1) ≈ L(9.1) = 3 + 1 6(9.1 − 9) ≈ 3.0167. Figure 4.2.2: The local linear approximation to f(x) = √x at x =
