TI-30XS MultiView Alternative: Free Online Scientific Calculator

TI-30XS MultiView Alternative: Free Online Scientific Calculator: How to do fractions on a TI-30XS style keypad: enter 1, n/d (the fraction key on the Pro), 2, +, 1, n/d, 3, enter. The answer is 5/6. Press the answer-toggle key to see 0.833333333. A second press returns to the exact fraction. For a mixed number such as 2 1/2, use the second function U n/d between the whole-number and numerator parts. The linear expression remains editable beside the textbook preview. How to do statistics on a TI-30XS style keypad: press data to open L1–L3. Enter the observations in L1, separated with spaces, then choose Calculate 1-Var statistics. Enter optional frequencies in the second field. Press enter to show the mean, population deviation and sample deviation. For separate statistics or regression, press 2nd then data and choose a menu item. Keep paired X and Y lists in the same order. How to do nCr on a TI-30XS style keypad: enter 5, choose nCr, enter 2, then enter. On the MultiView, nCr is item 2 in prb. On the Pro, repeated presses of the probability key cycle !, nCr and nPr. The result is 10. For trigonometry in degrees, press mode, choose DEG, return with 2nd mode, and enter sin, 30, enter. The exact result is 1/2. Always check the angle mode before comparing a homework answer. The arrow pad selects menu items and recalls history; enter selects the highlighted item. Use sto→ followed by a variable key to save a value, and 2nd sto→ to recall it. How to use a table on a TI-30XS style keypad: press table and enter f(x), the starting X and the step. Enter shows seven value pairs. Change the start or step to inspect another interval. The variable key cycles x, y, z, t, a, b and c on consecutive presses. Insert an operator to finish the selected variable before choosing another one. For hyperbolic functions, press 2nd π and choose sinh, cosh or tanh. sinh(1) gives 1.175201194. Unlike ordinary trig functions, hyperbolic functions do not use the degree setting. What is not supported: this calculator does not run device software. The editors use plain expression and coefficient fields rather than every device prompt. The full device conversion menu and the complete device error-position flow are not available. Auto tables show seven rows at a time; Ask for x evaluates a chosen input. Matrix operations use separate row fields. List formulas can reference a directly entered list with =L1*2; chained formulas are not supported. Some advanced menu entries use simpler expression fields.
