## What is the equation of curves?

A curve can be represented in a graph using the help of equations. Let’s understand it with the help of some examples. The equation y = x2 represents a parabola in the cartesian plane, as shown below. The equation ax2 + by2 = c is the general equation for an ellipse.

### What is a butterfly plot?

Butterfly plot is an effective graphical representation for comparing two treatment responses for the same subject across different time points. Butterfly plots are drawn across a centered axis to separate two treatment responses in one picture.

#### Which of the following is the equation of a plane?

The vector form of equation of a plane is →r. ^n=d r → . n ^ = d .

**How do you find the equation of a normal plane?**

So the equation of the normal plane is y = 1 − z y=1-z y=1−z. we’ll need to find the magnitude of the derivative first, so that we can plug it into the denominator. We already found r ′ ( t ) r'(t) r′(t) when we were working on the equation of the normal plane.

**What are the steps to solve an equation?**

The following steps provide a good method to use when solving linear equations.

- Simplify each side of the equation by removing parentheses and combining like terms.
- Use addition or subtraction to isolate the variable term on one side of the equation.
- Use multiplication or division to solve for the variable.

## How do you read a butterfly chart?

A Butterfly Chart (also called Tornado Chart) is a type of bar chart where two sets of data series are displayed side by side. It gives a quick glance of the difference between two groups with same parameters.

### How do you graph a spiral on a TI-84?

Press the mode key, then press the arrow down button until you get to FUNCTION, then move right 2 spaces to POLAR and press the enter key. Now you are in the right mood mode 😊. Use your calculator to graph a spiral that’s sure to catch the eye of that special someone. Press the y= key.

#### How do you write an equation for a plane?

The equation of plane having a unit normal vector and at a distance from the origin is →r. ^n r → . n ^ = d. The equation of plane passing through three non collinear points is (→r−→a)[(→b−→a)×(→c−→a)]=0 ( r → − a → ) [ ( b → − a → ) × ( c → − a → ) ] = 0 .
