SinX is defined for any angles [0,∞) ?
SinX is defined for any angles [0,∞)
Ok, the domain of sinX is -∞< x < ∞
Someone said "You are confused due to fact that Sin(-x)= - sin(x)." Does it mean that just because sinX is not exactly -sinX, sinX will be undefined for all the negative angles since they will produce negative sine function values and we are only interested in positive sine function?
Thanks.
