Wrath of Math | Limit of (sqrt(x^2+9)-3)/x^2 as x approaches 0 (Using Conjugate) | Calculus 1 Exercises @WrathofMath | Uploaded 2 months ago | Updated 8 hours ago
We evaluate the limit of (sqrt(x^2+9)-3)/x^2 by multiplying and dividing by the conjugate then using substitution once the indeterminate form has been changed by the conjugate.
