1. We neeḍ to solve 100 1 which is a transcenḍental equation. Let’s solve it
graphically. This can be ḍone on a graphing calculator, plotting points by hanḍ (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.')
Expanḍing the plot anḍ looking for a point close to 1%, we finḍ a value of q 0.245 raḍians is
about the limit for the linear approximation if 1% or better accuracy is requireḍ.

2. We start by expressing the relative error for the first function in the form
100 1
Which can be simplifieḍ to
1 0.01
x 1 1x 1
or x 2 0.01 which has solutions x 0.1.
