Ekvationen sin (x). cos (x) = ½ är krånglig att lösa eftersom vi har x på två olika ställen - i en sinusfunktion och i en cosinusfunktion samtidigt. Vi kan alltså varken använda arcsin eller arccos för att få fram ett "naket" x, för det skulle göra att det andra x-et blir ännu mer invecklat i krångligheter.

They run contrary to the seven virtues of Christianity so we If you're trying to figure out what x squared plus x squared equals, you may wonder why there are letters in a math problem. That's because, in the case of an equation like this, x can be whatever you want it to be. To find out what x squar The cosine of x is zero at values π/2, 3π/2, 5π/2, 7π/2 radians, and so on. Since this is a periodic function, cosine of x equals zero The cosine of x is zero at values π/2, 3π/2, 5π/2, 7π/2 radians, and so on.
