Graphing a Trigonometric Graph Sine with a Reflection
👉 Learn how to graph a sine function. To graph a sine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the...

What Are Structural Isomers
In this video we will look at some different structures of butane - so they all have 4 carbons but just arranged differently. We will also look at the the 5 different isomers for hexane - they all have 6 carbons (and hence are hexane...
