Given the unknown number n do the following. Write an expression for the sum of this number squared and 10.
Evaluate the expression you wrote for n=3.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
