In other words, what angle x would satisfy sin(x) = 1 2? Nettet7 Limits of trigonometric functions at infinity Since sinxand cosxoscillate between −1and 1as x→ ±∞, neither of these functions has a limit at infinity. However, limits like lim x→+∞ sinx x might exist. Indeed, as x→ +∞, the value of sinxis between −1and 1, and the value of xincreases without bound, so
