How can I remember my trigonometric identities?
You can use the acronym SOH CAH TOA in order to remember you basic trigonometric identities. SOH is Sin= OPPOSITE/Hypotenuse, Cos=Adjacent/Hypotenuse, and Tan=OPPOSITE/ADJACENT.
When will we need to use Scientific Notation?
Scientific Notation is used to write extremely small and large numbers more efficiently. Scientist do not have all the time in the world to write down numbers in Standard Form, so this is why we use Scientific Notation.
How do I solve for a variable in a equation?
First you must understand the properties of equality in order to isolate the variable. The properties of equality will be your tool in order to cancel out all the terms except for the variable.
