# Voltage and Current Dividers

Voltage and Current Dividers Voltage Divider: A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics. It is interesting and useful to consider Read more about Voltage and Current Dividers[…]

# MAXIMA AND MINIMA PROBLEMS

MAXIMA AND MINIMA PROBLEMS 1. Without using the derivative, show that f(x) = (½)x is strictly decreasing on R. Solution: Given that f(x) = (½)x Let x₁, x₂ ϵ R Let x₁ < x₂ ⇒ (½)x₁ > (½)x₂ ⇒ f(x₁) > f(x₂). ∴ f is strictly decreasing on R. 2. Without using the derivative, show Read more about MAXIMA AND MINIMA PROBLEMS[…]
