Features and Functions of our Online Scientific Calculator

Sign	Using Purpose
Rad/Deg	The "Mode" setting on our online calculator allows you to toggle between measuring angles in radians or degrees. Basically, it stays in radian by default. If you need to calculate in degrees, just click on the mode and it will turn on the degree mode.
()	Brackets, or parentheses, are used in our calculator to group and prioritize calculations. Besides, it ensures that operations within the brackets are evaluated before those outside, helping to clarify and control the order of operations.
x²	The "X squared" function raises a number to the power of 2, effectively squaring it, which is commonly used for calculations involving areas and squares.
x³	"X cubed" raises a number to the power of 3, cubing it, often used in various mathematical applications, including volume calculations.
³√x	This function calculates the cube root of a number, finding the value that, when multiplied by itself three times, gives the original number.
√x	It computes the square root of a number, helping to find the value that, when squared, results in the given number.
1/x	The inverse function calculates the reciprocal of a number, which is 1 divided by the original number. It's essential for various mathematical operations and proportions.
sin	"Sine" is a trigonometric function used to find the ratio of the length of the side opposite an angle in a right triangle to the length of the triangle's hypotenuse.
cos	"Cosine" is another trigonometric function that calculates the ratio of the length of the side adjacent to an angle in a right triangle to the length of the hypotenuse.
tan	"Tangent" is a trigonometric function that determines the ratio of the length of the side opposite an angle in a right triangle to the side adjacent to that angle.
ln	The "Natural log" function (ln) calculates the logarithm of a number to the base 'e' (Euler's number), which is approximately 2.71828, and is commonly used in various scientific and mathematical contexts.
log	"Logarithm" calculates the logarithm of a number with a specified base, which is valuable for various mathematical and engineering calculations.
AC	"AC" or "All Clear" is used to clear the calculator's memory and reset it to its initial state, typically before starting a new calculation.
Del	The "Delete" function removes the most recently entered digit or character, helping to correct input errors.
x	The multiplication symbol (x) is used to perform multiplication operations between numbers.
÷	The division symbol (÷) is used for dividing one number by another in mathematical calculations.
+	The addition symbol (+) is employed to add numbers together, determining their sum.
-	The subtraction symbol (-) is used to subtract one number from another, finding the difference between them.
π	"PI" represents the mathematical constant π (pi), which is approximately 3.14159…. and is used in calculations involving circles and trigonometry. Our calculator shows Math.PI (while clicking on π) for better output. Please consider it.
Ans	The "Answer" function typically recalls the result of the previous calculation, allowing it to be used in subsequent operations.
=	The equal sign (=) is used to signify the end of a mathematical expression and to compute the result of the calculation based on the entered expression.

FAQs for the Scientific Calculator Online

Q1) How do I switch between radians and degrees in the calculator?

Answer: You can change the mode from radians to degrees or vice versa by using the "Mode" function on the calculator. It allows you to set the desired angle measurement unit for your calculations.

Q2) What's the purpose of the brackets (parentheses) on the calculator?

Answer: Brackets are used to group and prioritize calculations. They ensure that operations within the brackets are evaluated first, helping to control the order of operations in complex expressions.

Q3) How can I square a number using the calculator?

Answer: To square a number, you can use the "X squared" (x²) function. Enter the number you want to square, and then press the "X squared" button to calculate its square.

Q4) What's the difference between "X cubed" and "Cube root x" functions?

Answer: "X cubed" (x³) raises a number to the power of 3, effectively cubing it, while "Cube root x" (³√x) finds the cube root of a number, which is the number that, when cubed, equals the original value.

Q5) How can I calculate the square root of a number on the calculator?

Answer: You can find the square root of a number by using the "root x" (√x) function. Enter the number, and then press the "Root x" button to calculate its square root.

Q6): What does the "Inverse of x" function do on the online calculator?

Answer: The "Inverse of x" (1/x) function calculates the reciprocal of a number. It is used to find the multiplicative inverse of a value, which is 1 divided by the original number.

Q7) How do I use the trigonometric functions on the calculator?

Answer: The calculator provides trigonometric functions such as "sine" (sin), "cosine" (cos), and "tangent" (tan) to calculate trigonometric ratios. Enter the angle in the desired unit (radians or degrees), and then press the corresponding trigonometric function button to calculate the ratio.

Q8) What's the purpose of the "natural log" (ln) function on the calculator?

Answer: The "natural log" (ln) function calculates the logarithm of a number to the base 'e' (Euler's number). It's commonly used in various scientific and mathematical applications, especially in calculus and exponential growth problems.

Q9) How do I clear the calculator's memory and start a new calculation?

Answer: To clear the calculator's memory and reset it to its initial state, use the "AC" (All Clear) function. This ensures that previous calculations do not affect your current one.

Q10) Can I correct an input error on the calculator?

Answer: Yes, you can correct input errors by using the "Delete" (Del) function. It removes the most recently entered digit or character, allowing you to make adjustments to your input.
