Determine the lowest positive root of f(x) =[7sin(x)e^(-x)]-1 a) newton-raphson method (xi=0.3) b) secant method (xi-1=0.5 and xi=0.

Determine the lowest positive root of f(x) =[7sin(x)e^(-x)]-1

a) newton-raphson method (xi=0.3)
b) secant method (xi-1=0.5 and xi=0.4)

for both methods, plot a true error, et and an approximated error, ea
(log scale) versus iteration numbers and discuss the rate of convergence.
