It looks equivalent.
Do the Pythagorean theorem on the triangle shown.
2.1^2-1.4^2
4.2-1.96=2.24
Sqrt of 2.24 is 1.496 or 1.5
Now multiply this by 2 to get the length of x

9n 15n
Keep, change, flip
- Keep the -4/9n
- Change the division sign to a multiplication sign
- Flip the 1/15n to 15n/1
-4 15n
--- * ---
9n 1
Cross simplify.
9n divided by 3 is 3n.
15n divided by 3 is 5n.
-4 5n

Step-by-step explanation:
Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α
