√ · sqrt
Type sqrt, then the radicand. Arrows move inside and outside roots.
sqrt → √ sqrt(9) → 3
xⁿ · ^
^ opens an exponent. → or Space leaves it. Use parentheses for a multi-term exponent. Powers precede a leading minus.
x^2 2^(3+1) → 16 -2^2 → -4
a/b · /
/ creates a fraction. Arrows move between numerator and denominator. Adjacent numbers and brackets multiply.
1/2 + 1/3 → 5/6 2(3+4) → 14
sin · log · π
Use the math keyboard for functions. log is base 10; ln is natural log. Trigonometry uses the selected angle unit.
sin(x), cos(x), tan(x), arcsin(x), arccos(x), arctan(x)
ln(x), log(x), exp(x), abs(x), floor(x), ceil(x)
pi, e · 5! → 120
← → · ⌫
Arrow keys move through a formula. Backspace deletes. Enter calculates or solves. Use the keyboard icon on touch devices.
← → ↑ ↓ Space Backspace Enter
f(x) · y=
The grapher supports eight real functions. Name rows f, g, h, d, etc.; call d(x) or d(2x). a, b, c are shared sliders. The solver supports real linear/quadratic equations only.
y = a·x² + b·x + c x² - 5x + 6 = 0
