How this calculation works
Enter an expression with explicit multiplication such as 2*pi. The parser supports sin, cos, tan, sec, csc, cot, sqrt, abs, exp, log and ln. Log and ln both use base e.
Parentheses and functions evaluate first, followed by powers, multiplication or division, and addition or subtraction.A worked example
In degrees, sin(30) is 0.5. Adding 2 cubed gives 8.5.
Good to know
Real finite arithmetic with floating-point precision. The parser accepts up to 500 characters, a limited function set and explicit multiplication.
How the inputs affect the result
Use parentheses around a negative base before raising it to a power. For example, (−2)^2 and −2^2 have different meanings. Press Enter in the expression field to calculate.
The same angle can be entered as pi/6 in radian mode.

A few questions, answered
Does the angle setting affect logarithms?
The setting only changes the argument units of trigonometric functions. For a base-ten logarithm enter log(x)/log(10), replacing x with a number.
What does the “Radians with pi” setting illustrate?
The same angle can be entered as pi/6 in radian mode.
