Issolvi P=acos5θ

$$P = a \cos 5 \theta$$

Solvi għal a

$$\left\{\begin{matrix}a=\frac{P}{\cos(5\theta )}\text{, }&\nexists n_{1}\in \mathrm{Z}\text{ : }\theta =\frac{\pi n_{1}}{5}+\frac{\pi }{10}\\a\in \mathrm{R}\text{, }&P=0\text{ and }\exists n_{1}\in \mathrm{Z}\text{ : }\theta =\frac{\pi n_{1}}{5}+\frac{\pi }{10}\end{matrix}\right.$$

Passi biex Issolvi l-Ekwazzjoni Lineari

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

$$a\cos(5\theta )=P$$

L-ekwazzjoni hija f'forma standard.

$$\cos(5\theta )a=P$$

Iddividi ż-żewġ naħat b'\cos(5\theta ).

$$\frac{\cos(5\theta )a}{\cos(5\theta )}=\frac{P}{\cos(5\theta )}$$

Meta tiddividi b'\cos(5\theta ) titneħħa l-multiplikazzjoni b'\cos(5\theta ).

$$a=\frac{P}{\cos(5\theta )}$$

Solvi għal P

$$P=a\cos(5\theta )$$
