Scientific calculator quick examples
DEG/RAD mode guide
Use when angles are entered in degrees.
Use for radian expressions with pi or engineering formulas.
If the answer looks wrong, check DEG/RAD first.
Fraction and decimal input
Enter fractions with slash division.
Results are shown as decimals or scientific notation.
These are physical calculator display modes; this web calculator uses slash input and decimal output.
Scientific Calculator Guide
The scientific calculator supports trigonometry, log and ln, square roots, powers, factorials, percent, parentheses, pi, and DEG/RAD modes. Use DEG for sin(30), RAD for sin(pi/6), and slash notation such as 1/2 for fraction-style inputs.
How to Use the Scientific Calculator
- 1.Choose DEG or RAD angle mode. Use DEG for degree angles and RAD for expressions with pi.
- 2.Enter sin, cos, tan, log, ln, square root, powers, x!, parentheses, and numbers.
- 3.Use slash notation for fractions; S⇔D and MathO/LineO are physical calculator display modes, while this web calculator returns decimal or scientific notation.
Scientific Calculator FAQ
Are trigonometric functions supported?
Yes. sin, cos, tan, inverse trig, and hyperbolic functions are supported.
When should I use DEG or RAD?
Use DEG for degree inputs such as sin(30), and RAD for radian inputs such as sin(pi/6). Both examples evaluate to 0.5 in the correct mode.
How do I enter fractions?
Use division notation such as 1/2, 3/4, or 1/2+1/3. Results are shown as readable decimals or scientific notation.
Does it support S-D, MathO, or LineO fraction display?
S⇔D, MathO, and LineO are physical calculator display modes. This web calculator uses slash input and decimal or scientific notation output.
What is the difference between log and ln?
log is base-10 logarithm, while ln is natural logarithm. For example, log(100) is 2 and ln(e) is 1.
Are pi and factorial supported?
Yes. The pi button inserts the pi constant, and x! calculates integer factorials such as 5! = 120.
Are powers and square roots supported?
Yes. Use x^y for powers, the square root function for roots, and x! for factorials.
Can I enter complex formulas?
Common scientific expressions with parentheses, powers, logs, and square roots are supported.
