Evaluate the limit
Question 2 the limit of (1-cos(x))/(x^2) as x approaches 0. i applied l'Hospitals rule twice and came up with -1/2 my professor got positive 1/2 help me out.
-i know it has the form 0/0.
-after i applied LH rule the 1st time i got (0+1sinx)/(2x)
-LH applied twice i got (-cos(x))/(2) = -1/2
Also this problem has been troubling me is there a formula that could help me out? thanks everyone.
The formula for velocity depending on constant acceleration (gravity's) and initial velocity, which I don't remember right now (I'm a mathematician, not a physicist), but it looks something like , or stuff.
