Through the left focus F1 of hyperbola x ^ 2 / 3-y ^ 2 = 1, make the chord AB with inclination angle of π / 3. Find the perimeter of triangle f2ab

Through the left focus F1 of hyperbola x ^ 2 / 3-y ^ 2 = 1, make the chord AB with inclination angle of π / 3. Find the perimeter of triangle f2ab

Go through the left focus F1 of hyperbola x2-y2 / 3 = 1 and make the chord AB with inclination angle of л / 6. Find (1) | AB and bring in the equation, ab = | x1-x2 | * under the root sign (1 + K ^ 2), then draw a picture to know that it is 2A
