A literal equation is one that has several letters or variables. Examples include the area of a circle (
) and the formula for speed (
). In this section you will learn how to solve literal equations in terms of one variable. To do this, you will use the principles you have learnt about solving equations and apply them to rearranging literal equations. Solving literal equations is also known as changing the subject of the formula.
You should bear the following in mind when solving literal equations:
We isolate the unknown by asking what is joined to it, how this is joined and we do the opposite operation (to both sides as a whole).
If the unknown variable is in two or more terms, then we take it out as a common factor.
If we have to take the square root of both sides, remember that there will be a positive and a negative answer.
If the unknown variable is in the denominator, then we find the lowest common denominator (LCD), multiply both sides by LCD and then continue to solve the problem.
The area of a triangle is
. What is the height of the triangle in terms of the base and area?
We rearrange the equation so that the height is on one side of the equals sign and the rest of the variables are on the other side of the equation.
The height of a triangle is given by:

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
