In quadrant ii, “smart,” only sine and its reciprocal. All the trig functions are positive in quadrant 1.

The classical definition of the cosecant function for real arguments is:
When is cosecant postive. In a formula, it is abbreviated to just. In quadrant ii, “smart,” only sine and its reciprocal function, cosecant, are. Secant, cosecant, and cotangent are trigonometric functions derived from the three elementary functions sine, cosine, and tangent.
The cosecant of an angle in a right‐angle triangle is the ratio of the length of the hypotenuse to the length of the opposite. Thus, in the first quadrant, where x and y coordinates are all positive, all six trigonometric functions have positive values. Sine and cosecant are positive in quadrant 2, tangent and cotangent are positive in quadrant 3, and cosine and secant are positive in quadrant 4.
In quadrant i, which is “a,” all of the six trigonometric functions are positive. If θ is in qii, then sine and cosecant are positive. In quadrant i, which is “a,” all of the six trigonometric functions are positive.
Where is csc not defined? This article will explain secant, cosecant, and cotangent. Sine and cosecant are positive in quadrant 2, tangent and cotangent are positive in quadrant 3, and cosine and secant are positive in quadrant 4.
Like the sine function, the cosecant function returns positive. Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to. That is, we can find the cosecant of angles greater than 180°, both positive and negative.
Solve cos θ = −0.85 we get the first. Sine and cosecant are positive in quadrant 2, tangent and cotangent are positive in quadrant 3,. Cosecant definition, (in a right triangle) the ratio of the hypotenuse to the side opposite a given angle.
Where is the cosecant function. The cosecant can be found using angles that go beyond the angles found in a right triangle. Is cosecant positive or negative in quadrant 3?
Unlike the tangent function however, the period of the cosecant function is three hundred and sixty degrees ( 360° ), or 2π.
