Question

answer the attached questions.

Answer 1

Answer:

a=60

b=150

c=0

d=60

e=120

Answer 2

Answer:

a) π/3 , 5π/3

b) 5π/4 , 7π/4

c) π/4 , 5π/4

d) π/4 , 3π/4

e)5π/6 , 7π/6

Step-by-step explanation:

Given-----> 0 ≤ x ≤ 2π

a) Cosx = 1/2

b) Sinx = - 1/√2

c) tanx = 1

d) tanx = √3

e) Cosx = - √3 / 2

Solution----> 1) Plzzz refer the attachment

2) a) We know that Cosx is positive in first and fourth quadrant

b) We know that Sinx is negative in third and fourth quadrant

c) and d) We know that tanx is positive in first and third quadrant

e) We know that Cosx is negative in second and third quadrant

By using this we find value of x in all parts of question
