If your results are coming out as fractions, press SHIFT MODE 2 to select the LineIO mode.

If your results are coming out as decimals but with not enough digits, press SHIFT MODE and then select either FIX or NORM for the display mode.

I assume you mean This equation contains two unknowns: k and a, so I cannot give you a numeric result, nor can a calculator. However, you can express k as a function of a, or a as a function of k: where ln is the natural logarithm base e=2.712818...

The MOD function simply returns the remainder that is left over after dividing the two numbers.

In this case, its possible to see quite easily that only 1×19937 can be taken from 24124 before the remainder is less than 19937. The MOD function is therefore the same as 24124 - 19937 = 4187.

In cases that are less obvious, do the division, ie 24124 ÷ 19937 = 1.210011536[34]
[The last two digits are hidden on the display but still used in subsequent calculations].
Then obtain the fractional part by subtracting 1 to give 0.210011536[34]. Then multiply the answer by 19937 to give 4187. Assuming that you haven't cleared the screen between each section of the calculation, the screen will show "Ans×19937 [=] 4187".

Press SHIFT then tan. The shifted function of the tan key is marked tan^-1 for inverse tangent, another name for the arctangent.

Press SHIFT MODE down-arrow 6. Use the left- and right-arrows to adjust the contrast. Press AC when done. If you can't get the contrast high enough to be easily readable, the battery might be low---try replacing the battery.

Press SHIFT cos then the value whose arccosine you want. For example, to find the arccosine of 0.5, press SHIFT cos . 5 =

Press SHIFT then the cos key.

It's the key marked "^", just below and right of the big circular cursor pad.

The calculator is telling you that the result is 7.5 times ten to the negative 3, or 0.0075 .If you want to see the result without the exponent, change the display mode. Press SHIFT [SETUP] 6 and then specify the number of digits you want after the decimal point.The D simply tells you that the calculator is set to Degrees. All trig functions will use degrees. If you want to change this, press SHIFT [SETUP] and select 4 for Radians or 5 for Grads.

Divide by 100. For example, take 40%. Divide 40 by 100 and get 0.40 .

Press SHIFT MODE 1 to put the calculator into MathIO mode.

Press MODE 4 to enter the BASE-N mode. Select the input base. Enter the number. Press =. Select the output base and see the result.

For all practical purposes, ratios involve nothing but the division of one quantity by another. Thus you use the division key. The first cited in a ratio is put in the numerator (dividend), the second named is put in the denominator (the divisor).2:3 translates as 2/3.

You don't need a calculator for this. Simply multiply both the numerator and denominator by 2 to get 2/30.

The key is marked "x-superscript-negative-one" and is located just below the "MODE" key, right of the big circular cursor pad.

Assuming that you have a number already stored in memory location X, and another number (lets call it "y") that you want to raise to the power of the number in memory X, then the required calculation is: y^X=

The key presses (after entering the value y) are [^][ALPHA][)][=]
