Step-by-step explanation:
<em>Let the "certain number" be </em><em>. </em>
( is a symbol for multiplication).
<em>Create a few equations and expressions:</em>
The sum of 12 and a certain number:
The product of 3 and the number:
The sum of 12 and a certain number is equal to the product of 3 and the number:
=
Solve!
12=3x-x
12=2x
x=6
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians
