NO CALCULATORS ALLOWED. No way… Before the invention of calculators, people solved complex calculations by converting values to logarithms in base 10, and at the time, this was the most efficient way of performing these calculations. By taking the logs of numbers, we are able to apply the “laws of logs”, which allow us to: … Continue reading

# What are the features of a cycle?

What would we do without cycles? Without the human life cycle, we would never grow or mature. If the water cycle stopped, everything would dry up and there would be no water for us to drink. If the carbon cycle stopped, organisms could not live. If the menstrual cycle stopped, there would be no more … Continue reading

# Mid year Math Class Reflection

How do you feel about your progress so far in math? Even though math is not my strongest subject, I think I have progressed. At the beginning of the school year I was very worried that I would not be able to keep up in 10+ at all, but now I feel much more comfortable. … Continue reading

# Modeling Inverse Variation

An inverse relationship means that as x increases, y decreases by a proportional amount, and vice versa. In real life, there are many phenomena that cause inverse variation relationships. Through research, I was able to find that the heart rate of an animal is inversely proportional to the life span of it. Here is a … Continue reading

# Complex Solutions

Is there any good reason to have complex solutions? Are there any practical applications of complex solutions to a quadratic? Before the discovery of complex numbers, the answer to a negative square root of any number was always “no solution”. But now we can use the concept of “imaginary numbers” to find solutions to equations … Continue reading
