If you got a different answer, it probably means that your scientific calculator is not in degree mode. On a scientific calculator, to find the sine of 30° for example, you type in 30, then press SIN to get 0.5.Perform a simple SIN function with an easy to remember answer.These scientific calculator functions are commonly used in Algebra. When you are using the SIN, COS, or TAN functions, you will have to keep in mind two different things: the order of the button presses, and radians versus degrees. Note that there’s usually a limit to how many previous answers are stored, so you can only use this method for recent calculations.

Use the Answer function to recall the last displayed answer to an equation.For example, if you just entered 2^4 and pressed ENTER (which equals 16), typing in -10 and pressing ENTER would subtract 10 from the solution (meaning it would be 16 - 10). You can perform another calculation on that answer by tying in the next operation. After completing a calculation, the last answer is automatically stored.There are a couple of different ways to use stored information: ![]() Use them in commercial designs under lifetime, perpetual & worldwide. ![]() Saving your results and pulling them back later is an essential skill for dealing with longer problems.
