Question

What are all the exact solutions of ? Give your answer in radians.

a) π/3, 2π/3
b) -π/4, π/4
c) 3π/2, -π/2
d) 4π/5, -4π/5

Answer 1

The exact solutions to the given equation in radians are: (a) π/3, 2π/3; (b) -π/4, π/4; (c) 3π/2, -π/2; (d) 4π/5, -4π/5.

Step-by-step explanation:

The exact solutions to the given equation are:

a) π/3, 2π/3

b) -π/4, π/4

c) 3π/2, -π/2

d) 4π/5, -4π/5

To convert these solutions to radians, it's necessary to divide the degree values by 180 and multiply by π. For example, π/3 in radians is (1/3)π, and -π/4 in radians is (-1/4)π.
