your calculator will never allow you to enter a negative exponent. so heres what you do.Any negative exponent of a number can be reversed and turned into a fraction for example 4^-1=1/4 or 8^-2=2/8=0.25. Hope this helps.

On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.

The Transfrm application for dynamic geometry is probably active in memory. You must purge it from RAM

1. Press APPS
2. Scroll Up or Down (Up is faster) to find Transfm.
3. Select it and press ENTER
4. Press the number corresponding to the option Uninstall.
5. Once the APP is kicked out of memory you will be able to draw multiple functions.

### How to solve an equation with negative exponent

You probably want to calculate the numerical value of some mathematical expression with numbers raised to negative exponents.
Just enter the expression as you would with positive exponents Except that before entering the value of an exponent press the change sign key, marked (-), or +/- or (+/-). Do not confuse the change sign with the usual minus sign, which is usually displayed bigger then the change sign. Make sure that the (-) is displayed before the value of the exponent. Use parentheses if necessary.

### Just got a SHARP EL-531X, it won't do simple calculations with scientific notation, It keep saying

To enter the power of 10 with exponent use the Exp key followed by the exponent. If the exponent is negative, you must use the negation key (-) not the - key (for subtraction).
When you press the Exp key you do not type in the 10.

### Im trying to graph a parametric equation and whenever the equation has an exponent/power in it the calculator says Syn error so i know how to graph x=2 cos T, y=2 sin T and similar equations without a...

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

### 825 - (659 - (410 - 360) x 684)= ?

This is a classic use of the old PEMDAS rule. The order of operation goes by Parenthesis, Exponents, Multiplication/Division, Addition/Subtration. Take it step by step to avoid getting mixed up.
The first operation done is (410-360) which = 50. New Equation: 825 - (659 - 50 x 684) = ? The second operation done is 50 * 684 which = 34200 New Equation: 825 - (659 - 34200) = ? The third operation done is 659 - 34200 which = -33541 New Equation: 825 - (-33541) = 825 + 33541 = ? it becomes +33541 because subtracting a negative is the same as adding the positive. The final operation done is 825 + 33541 which = 34366 Your Final Solution Is:
825 - (659 - (410 - 360) * 684) = 34366

### How do you make the calculator ti 30xa convert

I have a few questions and then I should be able to help you. In the equation you want to solve there is a letter g. Is this supposed to be there? Does this represent units such as grams? If this is the only units in this equation the answer will be mass not volume. Lets ignore the units and just punch in the numbers. Assuming the equation you want to solve is 3.70/2.50 x 10^-6. The buttons you need to push are 3.7/2.5 EE 6 [+/-] =. The EE button is the exponent button and the [+/-] button is the change sign button, located just below the 3. The change sign button changes the sign of the proceeding character, in this case it changes the 6 into a -6. This calculator will calculate the exponents before it does the multiplication or division so you don't need to use any parentheses for this equation. I hope this helps you out.
