as it is obvious base on the Taylor series or l'hopital's rule , answer the below equation is 1/2
Taylor series :
(1-cos(teta))/(teta^2)= 1/2! - (teata^2)/4!
and while teta wiling to zero others terms become zero and the answer is 1/2
(1-cos(teta))/(teta^2)= sin(teta)/(2*teta) =(1/2)*(cos(teta))
and again while teta wiling to zero answer is 1/2
but matlab act different and it gives right answer when you assume that teta is 0.01 or 0.001 but when you assume that teta is 0.00001 matlab give zero answer to this equation
is it my fault or something wrong with matlab and i really appreciated if some one can help me and if let me know if there is code for my problem
