cot[x]= -1
cot[x] = cos[x] / sin[x]
cos[x] / sin[x] = -1
cos[x] = -sin[x]
|cos[x]| = |sin[x]| at every multiple of Pi/4 + Pi/2. However, the signs disagree at 3Pi/4 + nPi, where n is an integer.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
1 + cot2x = csc2x
Cotangent(0.675 radians) = 84.88 approx.
The cotangent of 510 degrees is: -1.73205081
Cotangent of ∞ is not π/2. It's actually nonexistent since cotangent is the continually oscillating function.
The cotangent of 60 degrees is 1\(3^1\2).
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
cotangent(50) = 1/tangent(50) = 0.8391
For an angle, ?, the cotangent (or cot) of the angle is given bycot ? = 1/tan ?If ?=65
You don't have buttons for cotangent, secant, and cosecant because you don't need them. Just invert. Cotangent is 1 over tangent, secant is 1 over sine, and cosecant is 1 over cosine.
No, it is not. To be correct, the expression requires parenthesis, which are missing.
The cotangent is the reciprocal of the tangent, so simply calculate, on your scientific calculator, 1 / tan(68).
cot(45 deg) = 1.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Cotangent = 1/Tangent : Cosecant = 1/Sine Then, cot + 1 = (1/tan) + 1 = (cos/sin) + (sin/sin) = (cos + sin)/ sin. Now, cos² + sin² = 1 so for the statement to be valid the final expression would have to be : (cos² + sin² ) / sin = 1/sin. As this is not the case then, cot + 1 ≠ cosec. In fact, the relationship link is cot² + 1 = cosec²
1 + cot2x = csc2x
