Perform advanced mathematical calculations including trigonometry, logarithms, exponents, and more.
Use the on-screen buttons or your keyboard to enter mathematical expressions. The calculator supports parentheses for grouping operations.
Functions like sin, cos, tan, log, ln, and sqrt are available as dedicated buttons. Click the function, then enter the value.
Press "=" or "Calculate" to evaluate the expression. Use "C" or "Reset" to clear the display.
The scientific calculator evaluates standard mathematical expressions following the order of operations (PEMDAS/BODMAS):
Parentheses > Exponents > Multiplication/Division > Addition/Subtraction
Trigonometric functions use radians by default: sin(x), cos(x), tan(x). Logarithms: log(x) = base-10, ln(x) = natural log.
Example 1: Calculate sin(45°).
Example 2: Calculate log(1000).
By default, trigonometric functions use radians. Convert degrees to radians by multiplying by pi/180.
Addition, subtraction, multiplication, division, exponents, square roots, trigonometric functions (sin, cos, tan), logarithms (log, ln), and constants like pi and e.
Yes, you can nest parentheses to control the order of operations, for example: (2 + 3) x (7 - 1).
The calculator supports standard floating-point precision, which is sufficient for most scientific and engineering calculations.
