What Is a Scientific Calculator?

A scientific calculator is an advanced mathematical calculator designed to perform calculations beyond basic addition, subtraction, multiplication and division.

It can perform functions such as trigonometry, logarithms, powers, roots, factorials, percentages and other mathematical operations.

How to Use This Scientific Calculator

Step 1: Enter numbers using the calculator buttons.

Step 2: Select DEG for degree-based trigonometric calculations or RAD for radian mode.

Step 3: Use scientific functions such as sin, cos, tan, log, ln, √ and x!.

Step 4: Press = to calculate the result.

Scientific Calculator Functions

sin: Calculates the sine of an angle.
cos: Calculates the cosine of an angle.
tan: Calculates the tangent of an angle.
log: Calculates the base-10 logarithm.
ln: Calculates the natural logarithm.
√: Calculates the square root.
x²: Calculates the square of a number.
xʸ: Raises one number to another power.
x!: Calculates the factorial of a non-negative integer.
π: Inserts the mathematical constant pi.
e: Inserts Euler's number.
