Answer:
x=π/2 ,3π/2
Step-by-step explanation:
cot x(csc x+1)=0
either cot x=0
tanx=∞=tan (π/2)
x=π/2
or csc x=-1
or sin x=-1=-sin (π/2)=sin (π+π/2)=sin (3π/2)
x=3π/2
Answer:
x = π/2, 3π/2
Step-by-step explanation:
cosecxcotx + cotx = 0
cotx(cosecx + 1) = 0
cotx = 0
x = π/2,
π + π/2 = 3π/2
cosecx = -1
x = 3π/2
x = π/2, 3π/2
