What is the limit when t approaches 0 of tan8t?/tan5t Precalculus Limits Two-Sided Limits 1 Answer Shwetank Mauria Feb 21, 2017 #Lt(t->0)(tan8t)/(tan5t)=8/5# Explanation: Let us first find #Lt_(x->0)tanx/x# #Lt_(x->0)tanx/x=Lt_(x->0)(sinx)/(xcosx)# = #Lt_(x->0)(sinx)/x xx Lt_(x->0)1/cosx# = #1xx1=1# Hence #Lt_(t->0)(tan8t)/(tan5t)# = #Lt_(t->0)((tan8t)/(8t))/((tan5t)/(5t))xx(8t)/(5t)# = #(Lt_(8t->0)((tan8t)/(8t)))/(Lt_(5t->0)((tan5t)/(5t)))xx8/5# = #1/1xx8/5=8/5# Answer link Related questions What is a two-sided limit?
