Adjacent symbols multiply. EI multiplies defined variables E and I. An implicit factor such as x m prefers the unit; x*m uses variable m. The result menu changes only the display.

Type fractions and brackets directly in the formula field. Use sqrt(9m^2), sin(30deg), pi and e. Enter inserts a blank row below your expression.

Integrate with a local variable. Define f(k)=k^2, then F(x)=integrate(f(k),k,0,x). The bounds can have units; the variable k belongs only to the integrand.

integrate(k^2,k) displays a symbolic primitive with +C. Powers, sums, constant factors, 1/k, and sin, cos, exp with linear arguments are supported. Bounded integrals calculate numerical results.
