Trigonometric equation solver
This calculator can solve basic trigonometric equations such as: $\color{blue}{ \sin(x) = \frac{1}{2} }$ or $ \color{blue}{ \sqrt{2} \cos\left(-\frac{3x}{4}\right) - 1 = 0 } $.
The calculator will find exact or approximate solutions on custom range. Solution can be expressed either in radians or degrees.
solution
The solution of
$$\tan\left( -\frac{ 4 x }{ 3 } \right)=0.4$$is
$$ \color{blue}{x = -\frac{ 7207 \pi }{ 80 } + \frac{ 3 }{ 4 }\pi n}~~~\text{where}~~ n \in \mathbb Z $$
Solve equation $ \sin(2x)=\frac{\sqrt{3}}{2} ~~ \text{for} ~~ 0 \leq x \leq 360^\circ $.
Find all solutions of the equation $ \cos \left( \frac{3x}{2} \right) = -\frac{\sqrt{2}}{2}$. Express the results in degrees.
Find exact solutions of the equation $ \tan \left( -\frac{4x}{3} \right) = 0.4$. Express the results in radians.
Solve $ 2\sin \left( x \right) + \sqrt{2}= 0 ~~ \text{for} ~~ -180^\circ \leq x \leq 180^\circ $. Express the results in degrees.
Please tell me how can I make this better.
