## Is the TI-Nspire CX CAS allowed in college?

Owning a TI-Nspire CX handheld is an investment that students can use from middle school through high school and college for both math and science courses.

## Is using a calculator cheating?

If you can answer “yes” to this question, then the technology isn’t something you’re using to cheat. That being said, you always want to make sure that you actually can write the paper with the help. Using a calculator is very helpful, but it doesn’t (and shouldn’t) replace your ability to do math on your own.

**How do you find the tangent line?**

1) Find the first derivative of f(x). 2) Plug x value of the indicated point into f ‘(x) to find the slope at x. 3) Plug x value into f(x) to find the y coordinate of the tangent point. 4) Combine the slope from step 2 and point from step 3 using the point-slope formula to find the equation for the tangent line.

### How do you differentiate a sine and cosine graph?

In a cosine graph, a positive or negative number vertically flips the graph and determines whether the graph starts at the maximum (if it’s positive) or minimum (if it’s negative). For a sine graph, a positive or negative number vertically flips the graph like it does with a cosine graph.

### What is implicit plotting?

In the study of graph algorithms, an implicit graph representation (or more simply implicit graph) is a graph whose vertices or edges are not represented as explicit objects in a computer’s memory, but rather are determined algorithmically from some other input, for example a computable function.

**How do you know if a function is explicit or implicit?**

An implicit function is a function, written in terms of both dependent and independent variables, like y-3×2+2x+5 = 0. Whereas an explicit function is a function which is represented in terms of an independent variable.
