Algebra
Name Formula / Value Note
Quadratic Formula x = (-b +/- sqrt(b^2 - 4ac)) / 2a For ax^2+bx+c=0
Sum of roots alpha + beta = -b/a Vieta's formulas
Product of roots alpha * beta = c/a
Discriminant D = b^2 - 4ac D>0: two real roots
AP nth term a_n = a + (n-1)d
AP sum S_n = n/2 * [2a + (n-1)d] Also S_n = n/2(a+l)
Trigonometry
Name Formula / Value
Pythagorean identity sin^2(theta) + cos^2(theta) = 1
Identity 2 1 + tan^2(theta) = sec^2(theta)
Identity 3 1 + cot^2(theta) = cosec^2(theta)
sin 30 deg 1/2
cos 30 deg sqrt(3)/2
tan 45 deg 1
sin 60 deg sqrt(3)/2
