Start with the identity (sin a)2 + (cos a)2 = 1. Divide both sides by (sin a)2 to get
1 + (cot a)2 = (csc a)2. Then subtract 1 from both sides. (cot a)2 = (csc a)2 - 1.
1 + cot2x = csc2x
No.
One plus cosecant squared x is equal to cotangent squared x.
yes 1 + cot x^2 = csc x^2
Assuming that "secany" is meant to be secant, the answer is cosecant.
negative cotangent -- dcot(x)/dx=-csc^2(x)
No, it is not. To be correct, the expression requires parenthesis, which are missing.
Cotangent is a trigonometric function. It is the reciprocal of the tangent.
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 answer is 1. sin^2 x cos^2/sin^2 x 1/cos^2 cos^2 will be cancelled =1 sin^2 also will be cancelled=1 1/1 = 1
