a\cos(n\theta )=r
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
\cos(n\theta )a=r
Tenglama standart shaklda.
\frac{\cos(n\theta )a}{\cos(n\theta )}=\frac{r}{\cos(n\theta )}
Ikki tarafini \cos(n\theta ) ga bo‘ling.
a=\frac{r}{\cos(n\theta )}
\cos(n\theta ) ga bo'lish \cos(n\theta ) ga ko'paytirishni bekor qiladi.
