The ellipse x2 / 2 + y2 = 1 and the line L with slope 1 intersect at two points a and B, and F is the left focus. Find the maximum area of triangle Abf1

Let the equation of the straight line l be y = x + B and its intersection with the ellipse a (x1, Y1) B (X2, Y2), then the area of the triangle ABF is 1 / 2|b|y1-y2|
Substituting x = y-b into the elliptic equation, we get 3 / 2 ^ 2-by + B ^ 2 / 2-1 = 0, | y1-y2 | = under the root sign (Y1 + Y2) ^ 2-4y1y2 = under the root sign 4-14 / 9b ^ 2
The area of triangle ABF = 4-14 / 9b ^ 2 under 1 / 2 | B | radical = 4B ^ - 14 / 9b ^ 4 under 1 / 2 radical, so that B ^ 2 = t, it is easy to know 0=

The sum of the three simplest fractions is one and five seventh. They have the same denominator. The numerator is three adjacent natural numbers. What are the three fractions

1+5/7=12/7
12/7 /3=4/7
So the three numbers are 3 / 7 4 / 7 5 / 7

Why use comparative grade to express the superlative middle: comparative grade + any other + singular noun; comparative grade + the other + plural noun?

For example: he is teller than any other student in class
He is taller than the other students in class.
Any other means any one of the others, so in the singular, he is higher than any student in the class;
He is higher than the other students in the class

5 times the root number 1 / 5 + 1 / 2 times the root number 20 - 5 / 2 times the root number 1 / 5 + 45

5 times the root number 1 / 5 + 1 / 2 times the root number 20 - 5 / 2 times the root number 1 / 5 + 45
=Radical 5 + radical 5 - 1 / 2 radical 5 + 3 radical 5
=9 / 2 root 5

How can you tell a noun from a verb in English

Nouns are things: for example, ice cream and hamburger. Verbs are things to do: for example, eating and drinking are very simple. When judging ice cream, ice cream is something, so nouns judge eat is something to do, so verbs. Some of them are both ranking and verbs: color, it has both color and painting

It is known that, as shown in the figure, ad is vertical BC, eg is vertical BC, eg is vertical BC, eg is vertical g, eg intersects AB at point F, and the angle AFE is equal to angle E. try to explain the reason why ad bisects the angle BAC
 

AD⊥BC,EG⊥BC
AD//EG
∠CAD=∠E=∠AFE=∠BFG
AD//EG
∠BFG=∠BAD
SO
∠CAD=∠BAD
Ad bisector bac
