### Finding the area of a triangle in the coordinate Plane

I find the easiest way to solve these is to sketch them first (I'm a visual learner;) We get a nice right-angled triangle, with the right-angle at B. The formula for the area of a triangle is 1/2 * base* height or (base * height)/2.

We can use BC or AB as the base.

If we use BC as the base, the length is 9-4 or 5. The height is 6-2 or 4.

We can now but the base and the height in the formula to figure out the area.

Good luck.

### Solution of triangles

Do you mean how to work out the sides and angles? The most common formula is

A / sin A = B / sin B = C / sin C

Here you need 2 sides and one angle, or 2 angles and one side. There are several others, see

### How can you find the correct window settings on a TI-83 plus

Set the windows dimensions to Standard (Xmin=-10, Xmax=10, Ymin=-10, Ymax=1: Both are parabolas, and the interesting part is the neighborhood of the extremum (maximum or minimum) and the location of the zero.
The third curve varies very fast, so you will have to reduce the interval Xmin, Xmax. to see the neighborhood of the origin, where the minimum is. (Minimum is at (0,0).

### Representing a solution using

The 1/2 coefficient controls how wide the parabola is. A smaller number (ex: a fraction) creates a wider opening in the parabola, whereas a larger number (ex: 4) creates a more narrow parabola.

### Minimum or maximum values of a parabola

Follow these steps: graph the parabola and after that 2nd then CALC keypad. To find extreme value of the function select 3: min or 4: max options. Select the function and set left bound, right bound(using left and right arrows) by pressing ENTER. You can see images bellow for all these steps for the y=-2x^2+5x+3

1. step: graphing parabola

2. step: left or lower bound

3. step: right or upper bound

4.step: extreme value of the function

### Is the calculator suppossed to have "DEG" in the bottom right hand corner? I am trying to enter the numbers for the compound interest formula and I keep getting "Syntax Error" Is it because of the...

The DEG indicator on the screen is a reminder to the user that the ANGLE unit is in degrees. You can change the angle unit to Radian or Grads. That does not have any incidence on other calculations. It only affects the computation of trigonometric functions : sine, cosine, tangent, arc cosine, arc sine and arctangent. So if you have syntax error in the calculation of the interest formula, I can assure you it has NOTHING to do with the angle unit.
I do not see the formula you are trying to use, so I cannot be sure what you are doing wrong.
1. Possible wrong usage of the regular minus sign instead of the change sign (-) or (+/-)
2. Missing right parenthesis
3. A right parenthesis is inserted at the wrong place.
4. Incorrect use of the power function
I suggest you write the correct formula on paper and enter it step by step. A step is defined by an operation: multiplication, division, power. Start with the content of parentheses and work toward the outside. The last result is always the one stored in Answer memory (Ans).
