  Class 11th Formulas: Quadratic Equation Formula: If ax^2 + bx + c = 0, then x = [-b ± √(b^2 - 4ac)]/2a Arithmetic Progression (AP) Formula: nth term = a + (n - 1)d Sum of n terms = (n/2)[2a + (n-1)d] Geometric Progression (GP) Formula: nth term = ar^(n-1) Sum of n terms = a(1 - r^n)/(1 - r) Trigonometric Functions Formulas: sin^2A + cos^2A = 1 1 + tan^2A = sec^2A 1 + cot^2A = cosec^2A Coordinate Geometry Formulas: Distance Formula: √[(x2 - x1)^2 + (y2 - y1)^2] Midpoint Formula: ((x1 + x2)/2, (y1 + y2)/2) Section Formula: ((m1x2 + m2x1)/(m1 + m2), (m1y2 + m2y1)/(m1 + m2)) Class 12th Formulas: Matrices Formulas: Addition of Matrices: A + B = B + A Multiplication of Matrices: AB != BA in general Transpose of a Matrix: (A^T)i,j = A(j,i) Determinants Formulas: |A| = ∑(-1)i+j * ai,j * |M(i,j)| M(i,j) is the minor of ai,j C(i,j) is the cofactor of ai,j, C(i,j) = (-1)i+j*M(i,j) Differentiation Formulas: Derivative of sinx: cosx Derivative of cosx: -sinx Derivative of tanx: sec^2x Derivat...

  "Pure mathematics is, in its way, the poetry of logical ideas." - Albert Einstein "Do not worry about your difficulties in mathematics. I can assure you mine are still greater." - Albert Einstein "Mathematics is the music of reason." - James Joseph Sylvester "Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding." - William Paul Thurston "In mathematics, the art of proposing a question must be held of higher value than solving it." - Georg Cantor "Mathematics is the most beautiful and most powerful creation of the human spirit." - Stefan Banach "The study of mathematics, like the Nile, begins in minuteness but ends in magnificence." - Charles Caleb Colton "Mathematics is the language in which God has written the universe." - Galileo Galilei "Mathematics, rightly viewed, possesses not only truth but supreme beauty." - Bertrand Russell "Pure mathe...
