The graphs of trigonometric functions have several properties to elicit. To be able to graph these functions by hand, we have to understand them. Before we progress, take a look at this video that describes some of the basics of sine and cosine curves.
Quick Answer. Ng/ml stands for nanograms per milliliter. This unit of measurement is often used for lab test results. For example, results of lab tests taken to check the levels of progesterone in the human blood are measured in nanograms per milliliter. Continue Reading.
