14.2 I’m trying to take some square roots, and I’ve simplified the code down to main() { printf(“%f\n”, sqrt(144.)); } but I’m still getting crazy numbers. 14.3 I’m trying to do some simple trig, and I am #including , but the linker keeps complaining that functions like sin and cos are undefined. 14.4a My floating-point calculations are acting strangely and giving me different answers on different machines. 14.4b I’m sure I’ve got the trig functions declared correctly, but they’re still giving me wrong answers.
