// Flatten
t.flatten([

// Linspace
t.linspace(0, 100, 10) // => [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]

// Range
t.range(10) // => [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

// Reshape

// Function
t.f("x", "2*x+1") // => TheoremJS function object

// Run
t.run(f, x) // = f(x)

// Polynomial
t.polynomial(2, 1) // f(x) = 2x + 1
t.polynomial(3, 2, 1) // f(x) = 3x^2 + 2x + 1

// Find Roots
t.findRoots(t.polynomial(1, -1, -1)) // => ['(1 + Math.sqrt(5)) / 2', '(1 - Math.sqrt(5)) / 2']

// Numeral Solve
t.numeralSolve(t.f("x", "2*x+1"), 0) // => ['-0.5', 0] , Returns -0.5 with 0 error rate

// Y-Intercept
t.y_intercept(t.f("x", "2*x+1")) // => 1

/* Math Basic functions */

// Factorial (returns a BigNumber object)
t.factorial(5).toNumber() // => 120

// Pow (returns a BigNumber object)
t.pow(2, 8).toNumber() // => 256

// Root (returns a BigNumber object)
t.root(256, 8).toNumber() // => 2

// Sqrt (returns a BigNumber object)
t.sqrt(4).toNumber() // => 2

// Sigmoid (returns a BigNumber object)
t.sigmoid(0).toNumber() // => 0.5
