How do you get the decay factor from the decay rate?
If we have y=a(b)^t as the equation then take b from this equation case !: If b <1 then b=1-r r=1-b this r is the decay factor case 2:If b >1 then b=1+r r=b-1 this is the growth factor
How do you expand binomials A plus b to the degree of n?
It isnC0*A^n*b^0 + nC1*A^(n-1)*b^1 + ... + nCr*A^(n-r)*b^r + ... + nCn*A^0*b^n where nCr = n!/[r!*(n-r)!]

What is the formula for getting the length of an angle bisector?
Let the sides be a,b,c,(opposite to BC,AC,AB): Let the angle be enclosed at vertex A.Let R be the length of the angle bisector.The formula to find R is:cb= R*R + ([{(c-b)(c-b)-2bc.(cos A-1)}^1/2]/c+b)^2.cb
How do you find the unknown angle when one angle is given and the other angles are known in the form of ratios are given?
Suppose you are given one angle A and the ratio is R so that the other two angles are B and BxR.Then: A + B + BxR = 180.B (1 + R) = 180 - Aso the answer is B = (180 - A) / (1 + R)e.g. you are given A=60 and R=2so B = (180 - 60) / (1 + 2) = 40 and the last angle is 80.
