About this Calculator
A full-featured scientific calculator with trigonometric functions, logarithms, powers, roots, and parentheses support.
Formula & Calculations
Formula
Standard arithmetic and scientific function evaluationsWhere:
- + − × ÷=Basic arithmetic operations
- sin, cos, tan=Trigonometric functions (input in radians)
- log, ln=Logarithm base-10 and natural logarithm
- √, x², xʸ=Square root, square, and power functions
- π, e=Mathematical constants pi (≈3.14159) and e (≈2.71828)
Assumptions
- Trigonometric functions expect input in radians.
- Division by zero returns 'Error'.
- Square root of negative numbers returns 'Error'.
- Results are displayed with up to 10 decimal places of precision.
Calculation Examples
Example 1
Inputs:sin(π/2)
Result:1
The sine of π/2 radians (90 degrees) equals 1.
Example 2
Inputs:log(100) + ln(e²)
Result:4
log(100) = 2, ln(e²) = 2, sum = 4.
Frequently Asked Questions
What angle units does this calculator use?
All trigonometric functions (sin, cos, tan) operate in radians. To convert degrees to radians, multiply by π/180.
Can I use parentheses for grouping?
Yes. Use parentheses to control the order of operations. For example, (2+3)×4 = 20, while 2+3×4 = 14.
What does the 'AC' button do?
AC (All Clear) resets the entire expression and result, returning the display to zero.
