I'm having trouble figuring out how I'm supposed to find the force vectors for this problem. I know I'm supposed to use trig somehow but I can't wrap my head around this since I have no sides just angles.
How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
