Has anybody idea on what techniques I can apply on these limits?
at c and d I did direct substitution since there is no zero at the denominator. Is that correct?
a) I converted polar form and denominator became cos^2Theta+Sin^2theta = 1 so that limit exists
how about b?
no techniques I know work and I couldn't prove it DNE either.
