I know the answer but do i have to show you their phone numbers and send it out on the bay on open mic or no no
Answer:
-2/3 or 1/2
Step-by-step explanation:
both eqn equal to zero
then we know that
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
Always congruent due to the way the shape is built
