FutureStarr2nd Button on Scientific Calculator
The more important question is whether the ancillary features of adding a number on a scientific calculator would be worth the cost. For example, one might expect a calculator to automatically switch to a basic solver.
The log is the inverse function of raising a number by a power. It takes the input number (base) and the output number and calculates which number the base must be raised to the power of to produce the output -- e.g. x^n=y --> logy(x) = n (the y would be given in subscript) and this is stated "Log base y of x equals n." If you have a modern calculator, there should be a log button with two blank rectangles allowing you to input the base and the output to find the power. On an older calculator, however, you will need to use a "log-law" to convert it into an equation involving the log function (meaning log base 10). Do this by typing logy/logx to give answer n.This current number cruncher's skin is made with DIVs and CSS3 as it were. The greater part of those StyleSheet orders set aside a more drawn out effort to be delivered in Firefox. This is a motivation behind why the response season of the virtual console and the contribution through the 'genuine' console is by all accounts somewhat sluggish. Albeit not very sluggish so that I'd need to change the innovation to something different like genuine pictures or acknowledging it with material or SVG.
Trig Functions: When you're working with angles, keep in mind many calculators let you select whether to express the answer in degrees or radians. Then, you need to determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos, etc., button and then enter the number. How do you test this: Remember the sine of a 30-degree angle is 0.5. Enter 30 and then SIN and see if you get 0.5. No? Try SIN and then 30. If you get 0.5 using one of these methods, then you know which works. However, if you get -0.988 then your calculator is set to radian mode. To change to degrees, look for a MODE key. There is often an indicator of units written right up with the numerals to let you know what you're getting. (Source: www.thoughtco.com)
