![]() We can linearize the sqrt(x) at x = 4 to get the line y - 2 = 1/4(x - 4)
by plugging in 5 to this line we get y - 2 = 1/4(5-4) which simplifies to y = 1/4 + 2 therefore sqrt(5) is about 2.25, however this is an overestimate since sqrt(x) is concave down for the entire interval for which it is defined. Or just plug it into a calculator and get 2.2360679775... |

![]() That moment when you realize a square root is the same as ^(1/2).

Phi is such an insane number!!
Did you guys know that phi^2 = phi + 1 and phi^-1 = phi - 1

![]() figured out I'm terribly wrong
2.92401774 to the third power is apparently 25 though |
