In Δ ABC, right angled at B, expressions for sec C and cosec C is
AC/BC , AC/AB
AC/BC , AC/BC
AC/AB , AC/AB
AC/AB , AC/BC
Recall the trigonometric ratios
sec C = hypotenuseadjacentside and cosec C = hypotenuseoppositeside
sec C = ACBC and cosec C = ACAB
△ ABC, right angled at B, ∠ACB = 60∘, expressions for sec 60 and cosec 60 is
In triangle ABC, right angled at B, find the expressions of cos A and sin C.
In △ ABC, right angled at B, ∠ACB = 60∘, Values of sec C and cosec C are :
