Inserts a square root sign.

Returns the integral of an expression.

When one expression is used as an argument, this command returns the indenite integral with respect to x.

Optionally, you can specify the variable of integration and the bounds of a denite integral using three

additional arguments.

Examples:

int(1/x) returns ln(abs(x))

int(sin(x),x,0,π) returns 2

int(1/(1-x^4),x,2,3)) returns -1/4*(2*atan(2)+ln(3))+1/4*(2*atan(3)-ln(2)+ln(4))

≠

Inequality test. Returns 1 if the left and right sides are not equal and 0 if they are equal.

≤

Less than or equal inequality test. Returns 1 if the left side of the inequality is less than the right side or if the

two sides are equal, and 0 otherwise.

≥

Greater than or equal inequality test. Returns 1 if the left side of the inequality is greater than the right side

or if the two sides are equal, and 0 otherwise.
