Answer:
f(x)=cscx
f(x+h)=csc(x+h)
f(x+h)−f(x)=csc(x+h)−cscx=1sin(x+h)−1sinx
=sinx−sin(x+h)sin(x+h)(sinx)
=2sin(x−x−h2)cos(x+x+h2)sin(x+h)(sinx)
=−2sin(h2)cos(2x+h2)sin(x+h)(sinx)
f′(x)=limh→0f(x+h)−f(x)h
=limh→0−2sin(h2)cos(2x+h2)hsin(x+h)(sinx)
=−limh→0sin(h2)h2×limh→0cos(2x+h2)sin(x+h)sinx
=−cosxsin2x
=−cscxcotx

Answer:
the answer is C
Step-by-step explanation:
using her first part 2 kilometers in 18 minutes
total kilometers - 2
and total time - 18
so you would get:
k – 2 = (t – 18)
