Quadratic Formula - Answer-x = -b ± √(b² - 4ac)/2a


Pythagorean Theorem - Answer-a²+b²=c²


(a^x)(a^y) - Answer-a^(x + y)


a^x / a^y - Answer-a^(x - y)


(a^x)^y - Answer-a^xy
Sine rule - Answer-a/sinA = b/sinB = c/sinC


Cosine rule - Answer-a² = b² + c² - 2bcCosA


Triangle Area - Answer-1/2 ab sinC


Cos^2A + Sin^2A= - Answer-1


1+tan^2A= - Answer-sec^2A


cosec^2A - Answer-1 + cot^2A

, sin2A= - Answer-2sinAcosA


cos2A= - Answer-cos^2A-sin^2A


tan2A= - Answer-2tanA/


x = a^n - Answer-n = logA(x)


logAx + logAy - Answer-logA(xy)


kloga(x) - Answer-loga(x^k)


straight line formula - Answer-(y - y1) = m(x-x1)


perpendicular gradients are... - Answer-negative reciprocals
