# Overiť totožnosť. cotx 1 + cscx = cscx-1 cotx

(csc x + cot x)(csc x - cot x) = 1

LCD = (cscx-cotx)(cscx+cotx) ((tanx*cscx+tanx*cotx)-(sinx*cscx-sinx.cotx))/(csc^2x-cot^2x) ((1/cosx)+1)-(1-cosx))/1 (1/cosx 1.y=16(.25)^x 2.y=0.8(1.28)^x 3.y=17(1/5)^x''. What is the common and least multiples of 3 and 6? i want to know how to answer the question! Give a practical example of the use of inverse Mar 09, 2014 · Your values for cotx are correct. cotx=0 gives tanx=∞ so x=π/2 and x=3π/2. tanx=-1 gives x=nπ-π/4 and n=1 gives 3π/4 and n=2 gives x=7π/4.
