WebDescription. example. F = symsum (f,k,a,b) returns the sum of the series f with respect to the summation index k from the lower bound a to the upper bound b. If you do not specify k, symsum uses the variable determined by symvar as the summation index. If f is a constant, then the default variable is x. symsum (f,k, [a b]) or symsum (f,k, [a; b ... WebThen we can say that a (n+2) + b (n+1) = 1. a(n+2)+ b(n+ 1) = 1. An easy way to figure out the values of a a and b b is to plug in some easy numbers. For example, let n= -2 n = −2. Then we get 0a - b = 1 0a−b = 1, so b = -1 b = −1. If we let n = -1 n = −1, then we get a + 0b = 1 a+0b= 1, so a = 1 a= 1.
