![]() ![]() The cosine function is another trigonometric function that can be used to relate the angle of a right triangle to the ratio of the length of the side adjacent to the angle and the hypotenuse. The cosecant function is a reciprocal of the sine function. ![]() ![]() The sine function can be used in this scientific calculator by clicking the “sin” button. In a right-angled triangle, the sine function can be used to relate the angle to the ratio of the length of the side opposite the angle and the hypotenuse. ![]() Here are the trigonometric functions that you will encounter as you study mathematics and engineering: It could be as simple as solving an unknown value of a right-angled triangle or solving the instantaneous power absorbed by an electrical element. Trigonometric functions: In mathematics and in various fields of engineering, trigonometric functions are frequently used to solve different problems. Which is supposedly called an “obelus” - who knew? (x / y) Division, sometimes referred to as the quotient, is sometimes shown as a fraction, a “/” or the “÷” symbol. (x * y) Multiplication, the product or “times” is represented sometimes by an “x” and sometimes by an asterisk “*”. (x - y) Subtraction, the “minus” sign, or sometimes difference, is used to find the numerical separation between two numbers, thus the term “difference”. (x + y) Addition, also known as summing or, more colloquially, “plus” is used to sum numbers together. This calculator is optimized for either desktop or mobile use, making it a portable powerhouse or a reliable at-the-desk tool.īasic operations: Even the most advanced scientific calculator needs the basics in order to be useful - here are the most commonly used and basic functions: With the inclusion of many different features, easy access to a wide variety of scientific constants. Convenient quantity menu helps you find the right unit for your problem.This free, easy-to-use scientific calculator can be used for any of your calculation needs but it is specialized for usage by engineers and scientists.unlimited undo makes it easy to find mistakes and correct them.PhyS圜alc even handles complex numbers!.Quantity units are supported in all calculations.Calculations may be entered in full before evaluating.Intuitive, minimal buttons in portrait display for ease and speed of use.sin(angle).Ĭalculate the volume in milliliters of 5 grams of carbon dioxide gas at 300 K and 989 mbar.r^2Ĭalculate the height in yards of a kite on 200 feet of string and flying at an angle of 40° with the ground.Multiply 3 teaspoons by 10 and give the answer in fluid ouncesĬalculate the rest mass energy of the electron in kiloelectronvoltsĬalculate the area in acres of a circle that has a radius of 1 mile. PhyS圜alc's sole ambition is to be the world's best scientific "pocket" calculator.īelow are some sample inputs and outputs of progressive complexity.Īdd 2 centimeters and 2 inches and give the answer in centimentersĪdd 2 centimeters and 2 inches and give the answer in inches A student using PhyS圜alc soon understands the connections between the base SI quantities and all the derived quantities. With PhyS圜alc you’ll know right away that you entered the calculation wrong because the result will have the wrong units.Īs a teaching tool PhyS圜alc offers students better insights in the concepts of physical quantity, dimensionality, and units. A conventional calculator will also give you a numerical answer, even if you accidentally multiplied instead of dividing. Not only does PhyS圜alc save you time, it also saves you from mistakes. This means you can enter and read through the entire expression in full before calculating the result, helping you quickly identify and fix any input errors. PhyS圜alc uses a natural infix notation for calculations. Can't remember a unit symbol? PhyS圜alc helps you find and append commonly used units onto a number. PhyS圜alc is quick to learn and easy to use. This allows you to get numerical answers in the desired unit in a fraction of the time you'd spend on a conventional calculator. It even knows physical properties for elements and isotopes in the periodic table. On top of this great simplification, PhyS圜alc knows practically every fundamental physical constant. How is PhyS圜alc different from other calculators? It allows you to include unit symbols in your calculations, obtaining the answer in the desired unit without those extra unit conversion steps. PhyS圜alc is the next generation scientific and engineering calculator with units-it makes the others seem like slide rules. ![]()
