Issolvi P=a(1-cosθ)

$$P = a ( 1 - \cos \theta )$$

Solvi għal a

$$\left\{\begin{matrix}a=-\frac{P}{\cos(\theta )-1}\text{, }&\nexists n_{1}\in \mathrm{Z}\text{ : }\theta =2\pi n_{1}\\a\in \mathrm{R}\text{, }&P=0\text{ and }\exists n_{1}\in \mathrm{Z}\text{ : }\theta =2\pi n_{1}\end{matrix}\right.$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Ibdel in-naħat sabiex it-termini varjabbli kollha jkunu fuq in-naħa tax-xellug.

$$a\left(1-\cos(\theta )\right)=P$$

Uża l-propjetà distributtiva biex timmultiplika a b'1-\cos(\theta ).

$$a-a\cos(\theta )=P$$

Ikkombina t-termini kollha li fihom a.

$$\left(1-\cos(\theta )\right)a=P$$

L-ekwazzjoni hija f'forma standard.

$$\left(-\cos(\theta )+1\right)a=P$$

Iddividi ż-żewġ naħat b'1-\cos(\theta ).

$$\frac{\left(-\cos(\theta )+1\right)a}{-\cos(\theta )+1}=\frac{P}{-\cos(\theta )+1}$$

Meta tiddividi b'1-\cos(\theta ) titneħħa l-multiplikazzjoni b'1-\cos(\theta ).

$$a=\frac{P}{-\cos(\theta )+1}$$

Solvi għal P

$$P=a\left(-\cos(\theta )+1\right)$$
