Product Details
The TI-30Xa is a scientific calculator that can perform basic arithmetic operations, fractions, percentages, powers, roots, exponents, logarithms, trigonometry, and conversions. It can also do one-variable statistics, such as mean, standard deviation, and linear regression. It has a memory function that can store and recall one value. It does not have any graphing or programming capabilities.
The TI-30Xa is powered by a single LR44/76A battery that can last for up to two years of normal use. It has an automatic power-off feature that turns off the calculator after about five minutes of inactivity to conserve battery life. It also has a low-battery indicator that shows when the battery needs to be replaced.
The TI-30Xa has a hard plastic body with color-coded keys and a snap-on protective hard case. It measures 6 x 3.1 x 0.8 inches and weighs 4.8 ounces. It is approved for use on SAT, ACT, and AP exams.
Features and Benefits
The TI-30Xa has several features and benefits that make it a reliable and convenient calculator for general math and science purposes. Some of them are:
– One-line display: The TI-30Xa has a one-line display that shows up to 10 digits and two exponents. It also shows the current operation and the pending operation on the screen. This helps you keep track of your calculations and avoid errors.
– Fraction features: The TI-30Xa can handle fractions and mixed numbers in both input and output modes. You can enter fractions in traditional numerator/denominator format or in decimal format. You can also convert between fractions and decimals with the push of a button.
– Conversions: The TI-30Xa can perform various conversions between different units of measure, such as degrees/radians/grads, polar/rectangular coordinates, DMS/degrees angles, fraction/decimal numbers, and metric/English units.
– Scientific notation: The TI-30Xa can display numbers in scientific notation with up to two exponents. You can also enter numbers in scientific notation using the EE key. This allows you to work with very large or very small numbers easily.
– Trigonometry: The TI-30Xa can calculate sine, cosine, tangent, and their inverses in both degrees and radians modes. You can also use the DRG key to switch between modes quickly.
– Statistics: The TI-30Xa can perform one-variable statistics on a set of data points. You can enter up to 35 data points using the data key and then calculate the mean, standard deviation, sum, sum of squares, variance, minimum, maximum, median, and linear regression coefficients using the stat key.
– Memory: The TI-30Xa has a memory function that can store and recall one value using the STO and RCL keys. You can also use the M+ key to add the current result to the memory value or the M- key to subtract it.
Drawbacks
The TI-30Xa is not without some drawbacks that may limit its usefulness for some users. Some of them are:
– No graphing or programming: The TI-30Xa is not a graphing calculator and cannot display graphs or tables of functions. It also cannot perform any programming or complex calculations that require multiple variables or equations.
– No multi-line display: The TI-30Xa has only a one-line display that cannot show more than one calculation or result at a time. This may make it difficult to compare or review multiple expressions or values.
– No MathPrint mode: The TI-30Xa does not have a MathPrint mode that can display math expressions and symbols as they appear in textbooks. Instead, it uses parentheses and abbreviations to indicate functions and operations.
– No solar power: The TI-30Xa relies solely on battery power and does not have a solar panel that can extend its battery life or provide backup power.
