I'm sure this is right since limx→0+ cos(x) = 1 lim x → 0 + cos ( x) = 1 and limx→0+ x = 0 lim x → 0 + x = 0, but since limx→0+ x = 0 lim x → 0 + x = 0 I can't just say: Things I tried: expand the fraction and use L'Hospital's rule (This didn't seem to yield. Subtract 1 1 from both sides of the equation. x = arccos(−0. Similarly, general solution for cos x = 0 will be x = (2n+1)π/2, n∈I, as cos x has a value equal to 0 at π/2, 3π/2, 5π/2, -7π/2, -11π/2 etc.
