3  3 sin
1. We need to solve  100  1 which is a transcendental equation. Let’s solve it
3 sin
graphically. This can be done on a graphing calculator, plotting points by hand (with a
little iteration), or using MATLAB script similar to
 q  linspace(0, 0.5 *pi/ 2,1000);
 rel_err  100 *abs(3 *q-3 *sin(q))./sin(q)/ 3;
 plot(q,rel_err,'r.')

Expanding the plot and looking for a point close to 1%, we find a value of q  0.245 radians
is about the limit for the linear approximation if 1% or better accuracy is required.

2. We start by expressing the relative error for the first function in the form

1  x   
1 

100  1 x  1
1
1 x

Which can be simplified to

1  x 1  x   1  0.01
1

or x 2  0.01 which has solutions x  0.1.

3. We begin by rearranging VC  V0 (1  e t / ) to yield t   ln  1  C  where VC/V0 is
 V0 
specified but t is not. We proceed to construct the expression for relative error, using
 V  V
the approximation that ln 1  C    C :
 V0  V0

 V   VC 
   C    ln  1  
Relative Error  100   0   V0 
V
 V 
 ln  1  C 
 V0 

Mercifully, the time constant (τ) cancels in the numerator and denominator. Thus,

(0.1)  ln(0.1)
(a) Relative Error  100   5.1%
ln(0.1)
 (0.5)   ln(1  0.5)
(b) Relative Error  100   28%
 ln(1  0.5)
