Solve cos⁡(2x)=0\cos{\left(2 x \right)} = 0 for xx

The calculator will try to solve the equation cos⁡(2x)=0\cos{\left(2 x \right)} = 0 for xx (find the real and complex roots).
Leave empty for autodetection.
Optional.
If the interval is specified, the checkbox will be checked automatically.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Your Input

Solve the equation cos⁡(2x)=0\cos{\left(2 x \right)} = 0 for xx.

Answer

Real roots

x∈{π(n−14)  |  n∈Z}≈{3.141592653589793n−0.785398163397448  |  n∈Z}x\in\left\{\pi \left(n - \frac{1}{4}\right)\; \middle|\; n \in \mathbb{Z}\right\}\approx \left\{3.141592653589793 n - 0.785398163397448\; \middle|\; n \in \mathbb{Z}\right\}

x∈{π(n+14)  |  n∈Z}≈{3.141592653589793n+0.785398163397448  |  n∈Z}x\in\left\{\pi \left(n + \frac{1}{4}\right)\; \middle|\; n \in \mathbb{Z}\right\}\approx \left\{3.141592653589793 n + 0.785398163397448\; \middle|\; n \in \mathbb{Z}\right\}

Complex roots

It seems that there are no complex roots.
