Which quadrant does sin x lie in?

1. cos x = –1/2, x lies in the third quadrant. Since x lies in third quadrant, sin x is negative. Therefore 2. sin x = 3/5, x lies in the second quadrant. Since x lies in second quadrant, cos x is negative.

What quadrant is sin a=2/3 Cos B=3/4?

If sin A=2/3 cos B=3/4, angle A is in quadrant 2 and angle B is in quadrant 4. How do you evaluate sin (A-B) without find A and B? | Socratic If sin A=2/3 cos B=3/4, angle A is in quadrant 2 and angle B is in quadrant 4.

What is the range of angles in different quadrants?

Let’s see the angles in different Quadrants. In Quadrant 1 , angles are from 0 to 90°. In Quadrant 2 , angles are from 90 to 180°.

What are the trigonometry functions given by sin and cos?

If θ is an angle of a right-angled triangle, then the trigonometry functions are given by: sin θ = Opposite Side of angle θ/Hypotenuse cos θ = Adjacent Side of angle θ/Hypotenuse tan θ = Opposite Side of angle θ/Adjacent

How do you find the reciprocal of Sine Cos cos tan?

The reciprocal of sine, cos, and tan are cosecant (csc), secant (sec), and cotangent (cot) respectively. The formula of each of these functions are given as: Sec a = 1/ (cos a) = Hypotenuse/Adjacent = CA/AB Cosec a = 1/ (sin a) = Hypotenuse/Opposite = CA/CB

How do you find the co-function of sin 90 degrees?

The co-function or periodic identities can also be represented in degrees as: sin (90°−x) = cos x cos (90°−x) = sin x tan (90°−x) = cot x
