Question

If tan θ = -4,then sin θ is

Answer 1

Answer

Given, tan θ = -4/3

Given, tan θ = -4/3We know that tan θ = Opposite/Adjacent and tan is negative in the second and fourth quadrants.

Given, tan θ = -4/3We know that tan θ = Opposite/Adjacent and tan is negative in the second and fourth quadrants.sin is positive in the second quadrant and negative in the fourth quadrant.

Thus, sin θ can be positive or negative in this case.

Thus, sin θ can be positive or negative in this case.Also, by Pythagorean triple, hypotenuse = 5

Thus, sin θ can be positive or negative in this case.Also, by Pythagorean triple, hypotenuse = 5Therefore, sin θ = 4/5 or sin θ = -4/5

All the best :)

Answer 2

Answer:

the ans is -4/5
