Solve on the interval [0/2pi] 1-cos(theta) = (1/2)

Airida [17]

Answer:

Final answer is $x=\frac{\pi}{3}$ and $x=\frac{5\pi}{3}$ .

Step-by-step explanation:

Given equation is $1-\cos\left(\theta\right)=\frac{1}{2}$

Now we need to find the solution of $1-\cos\left(\theta\right)=\frac{1}{2}$ in given interval $[0, 2\pi ]$ .

$1-\cos\left(\theta\right)=\frac{1}{2}$

$-\cos\left(\theta\right)=\frac{1}{2}-1$

$-\cos\left(\theta\right)=-\frac{1}{2}$

$\cos\left(\theta\right)=\frac{1}{2}$

which gives $x=\frac{\pi}{3}$ and $x=\frac{5\pi}{3}$ in the given interval.

Hence final answer is $x=\frac{\pi}{3}$ and $x=\frac{5\pi}{3}$ .

Which polynomial is written in ascending order? t2 − t 4 t2 4 − t 4 t2 − t 4 − t t2

butalik [34]

In order to solve this, you have to look at the order for each of the variable terms. In this case t is your variablr
4t0=4 exponent is 0. −t1=−t exponent is 1. t2 exponent is 2. So you order them by exponents from least to greatest (ascending). 4−t+t2
