Solve System of Equations in R
a. a square numeric or complex matrix containing the coefficients of the linear system. Logical matrices are coerced to numeric. b. a numeric or complex vector or matrix giving the right-hand
Basic Math. Solve for r I=prt. I = prt I = p r t. Rewrite the equation as prt = I p r t = I. prt = I p r t = I. Divide each term in prt = I p r t = I by pt p t and simplify. Tap for more steps r = I pt r = I p t.
There are plenty of optimization and root finding libraries for R link here. But in native R: But in native R: fnToFindRoot = function(r) { n <- c(2:10) return(abs(-100/(r+1)+sum((100
