    Console

    Type on the entry line. The math renders as you type, LyX-style: type LaTeX commands (\int, \frac, \begin{pmatrix}) or the shortcuts below, and Tab jumps between boxes.

    Starting a line with + ^ or \cdot continues from the last answer (ans), like a TI.

    What a line does

    Complex numbers & matrices

    i, e^{i\pi}, 2\angle\frac{\pi}{3} (polar entry), |z|, \arg z, \Re z, \Im z, z^* or \overline{z} (conjugate), polar(z), rect(z). The Complex menu shows results as a+bi or reiθ.

    Matrices: A^{-1}, A^T, A^\dagger or A^H (conjugate transpose), A^* (conjugate), \det A, AB, u\cdot v. The Matrix ▾ menu lists every matrix operation. Ctrl+Enter adds a row; right-click inside a matrix to add columns.

    Graph

    The list under the graph is separate from the console. To add a line, type it there, press Graph ↗, or use Shift+Enter. It can use anything defined in the console. Letters that aren't defined become sliders, e.g. a\sin(bx). It draws y=f(x), x=f(y), implicit curves, inequalities, polar r=f(\theta), parametric (x(t),y(t)), points, and surfaces z=f(x,y) on the 3D tab. 1:1 (2D) keeps x and y at the same scale so circles stay round; 3D glasses (3D tab) draws the surface as a red/cyan anaglyph (red lens on the left eye).
