Calculators and Formulas (beta)

Calculus Derivative (in terms of x)
ƒ(x) = axⁿ
ƒ′(x) = na·x⁽ⁿ⁻¹⁾
Area Area of a Circle
A = πr² =
Area of a Circle Sector
A = πr² × (arc°/360) =
Area of a Rectangle
A = ℓ × w =
Area of a Triangle
A = (b × h) / 2 =
Area of a Rhombus
A = D × d =
Area of a Trapezoid
A = S × s / 2h =
Area of a Regular Polygon
A = (p × a) / 2 =
Surface Area of a Sphere
A = 4πr² =
Total Surface Area of a Cone
A = Base Area + Lateral Area = πr² + πrh =

Volume of a Sphere
V = (4πr³)/3 =
Other Equation of a Circle
ƒ′(x) = (x – h)² + (y – k)² = r²,
where circle center: (h,k)
Circumference of a Circle
C = 2πr =
