Hi guys I was wondering how I can understand if the sin and the cos has essential singularities. for instance if I want to understand if 0 which singularity is i, can write the Laurent series only of the sin (centred in 0) and see how it works , or MUST write the Laurent series of all the function (centered in zero) ?
Same for cos , help I want to understand this topic very well. Thk.
∫+∂Dsin(1z)cos(1z−2)z−5dz
