Euler’s formula

For every real number $x$ ,

e^{ix} = \cos x + i\sin x

e^{i x}

e^{i x} =

e^{i x} = cos

e^{i x} = cos x

e^{i x} = cos x +

e^{i x} = cos x + i

e^{i x} = cos x + i sin

e^{i x} = cos x + i sin x

e^{i x} = cos x + i sin x

At $x = π$ it becomes Euler’s identity, $e^{iπ} + 1 = 0$ .

Hamlet

Act III, Scene 1

HAMLET.

To be, or not to be, that is the question:
Whether ’tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them?

To die—to sleep, no more.

My liege and madam, to expostulate What majesty should be, what duty is, Why day is day, night night, and time is time Were nothing but to waste night, day and time.

Your noble son is mad.

To die—to sleep, No more; and by a sleep to say we end The heart-ache, and the thousand natural shocks That flesh is heir to.

To die is to sleep, and sleep ends the heartache and the body’s thousand shocks.

Does it work offline?

The editor does, completely. Textus AI needs your provider, unless you run a local model.
