सोडोवचें 4sin(θ)cos(θ)=2sin(θ)4x

$$4 \sin ( \theta ) \cos ( \theta ) = 2 \sin ( \theta ) 4x$$

x खातीर सोडोवचें

$$\left\{\begin{matrix}\\x=\frac{\cos(\theta )}{2}\text{, }&\text{unconditionally}\\x\in \mathrm{R}\text{, }&\exists n_{1}\in \mathrm{Z}\text{ : }\theta =\pi n_{1}\end{matrix}\right.$$

दोनूय कुशींनी 4 रद्द करचो.

$$\sin(\theta )\cos(\theta )=2\sin(\theta )x$$

कुशी हाणच्यो ताका लागून बरोबर चिन्नाच्या दाव्यान सगळी विशम संज्ञा येतली.

$$2\sin(\theta )x=\sin(\theta )\cos(\theta )$$

समिकरण प्रमाणिक स्वरूपांत आसा.

$$2\sin(\theta )x=\frac{1}{2}\sin(2\theta )$$

दोनुय कुशींक 2\sin(\theta ) न भाग लावचो.

$$\frac{2\sin(\theta )x}{2\sin(\theta )}=\frac{\sin(2\theta )}{2\times 2\sin(\theta )}$$

2\sin(\theta ) वरवीं भागाकार केल्यार 2\sin(\theta ) वरवीं केल्लो गुणाकार काडटा.

$$x=\frac{\sin(2\theta )}{2\times 2\sin(\theta )}$$

2\sin(\theta ) न\frac{1}{2}\sin(2\theta ) क भाग लावचो.

$$x=\frac{\cos(\theta )}{2}$$

θ खातीर सोडोवचें

$$\left\{\begin{matrix}\\\theta =\pi n_{1}\text{, }n_{1}\in \mathrm{Z}\text{, }&\text{unconditionally}\\\theta =-\arccos(2x)+2\pi n_{2}\text{, }n_{2}\in \mathrm{Z}\text{; }\theta =\arccos(2x)+2\pi n_{3}\text{, }n_{3}\in \mathrm{Z}\text{, }&|x|\leq \frac{1}{2}\end{matrix}\right.$$
