Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
in trigonometry
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
sine, cosine, tangent, cosecant, secant and cotangent.
No, it does not.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
Trig identity... sin/cos = tangent
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
Yes, sine, cosine, tangent definitions are based on right triangles
The tangent of an angle theta is defined as sine(theta) divided by cosine(theta). Since the sine and cosine are Y and X on the unit circle, then tangent(theta) is Y divided by X. The tangent of a function at a point is the line going through that point which has slope equal to the first deriviative of the function at that point.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
That is the correct spelling of "tangent" (intersecting at one point, or sine divided by cosine, or opposite side over adjacent side).
Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '
No, it is not. To be correct, the expression requires parenthesis, which are missing.
It is a trigonometric function, equivalent to the sine of an angle divided by the cosine of the same angle.
