If you aren’t sure at this point about the shape of the graph, go back to Step 1 and choose a couple more x-values to complete the picture. Step 6:Check your work. You could use a graphing calculator: I used the one atDesmos.comto create the graphs here. If you can’t use a...
Step 2:Visit thenormal probability area indexand find a picture that looks like your graph. Follow the instructions on that page to find the z-value for the graph. The z-valueisthe probability.Tip:Step 1 is technically optional, but it’salwaysa good idea to sketch a graph when you’re...
I’ll give away here my position on this panel: We get assessments for non-CS majors wrong because we think about them as CS majors. Calling a non-major’s introductory computing course “CS0” is making the assumption that it’s the starting point for a sequence that goes on to CS1 ...
When you need to learn formulas, also learn the conditions for each formula (it might be something like "if x > 0"). Also draw a relevant diagram or graph each time you write the formula (it might be a parabola, or perhaps a circle). You will begin to associate the picture with ...
This function $$\frac{e^x - e^{-x}}{2}$$ is called the hyperbolic sine. I'll refer to it as "hypersine" for short. You could say it "splits the...
